1. Executive Summary

The Core Argument

Sartorius BioBrain is the automation and SCADA layer of the most complete bioprocessing ecosystem in the industry — a hardware-anchored, end-to-end portfolio spanning single-use upstream (Biostat STR, Biostat RM), benchtop multi-use (Biostat B-DCU), high-throughput screening (ambr 15 / ambr 250), PAT analytics (BioPAT), and downstream operations (Sartoflow TFF, Flexact DSP, AliquoT filling). QB Control is a SCADA-class, browser-based bioprocess platform that ships its own modular hardware (QB Modules) and software co-engineered as one system — and that deploys both on QB Edge (benchtop QB Modules) and on a standard industrial PC driving stainless-steel, PLC-based systems via OPC-UA for pilot- and production-grade installations.

These are overlapping but very different propositions. Sartorius is a vertically integrated, hardware-first powerhouse that sells a single accountable stack from screening to fill-finish. QB Control is a vendor-neutral turnkey hardware + software platform with ~40 pre-built services, native multi-vendor sensor support, a visual no-code recipe engine, built-in compliance scaffolding, and a lower total cost of ownership. The comparison is most relevant for lab-to-pilot upstream bioprocessing (150 mL – 50 L benchtop, plus stainless-steel pilot/production via PLC), where a buyer is choosing a control and automation platform for new builds, expansions, or modernization — and where the full Sartorius ecosystem is often more than the workflow requires.

Key Finding

QB Control does not replace Sartorius BioBrain in every scenario, and is honestly not trying to. Sartorius wins decisively at GMP production scale, at sub-150 mL ambr screening, and wherever a single-vendor, end-to-end upstream-plus-downstream stack is the requirement. QB Control replaces BioBrain where vendor neutrality, turnkey hardware, rapid deployment, and lower TCO matter more than ecosystem breadth — primarily lab-to-pilot upstream control and stainless-steel pilot cells. The sweet spot for QB Control as a BioBrain alternative is:

Scenario	QB Control Replaces BioBrain?	Value Driver
Lab-scale upstream (150 mL–10 L)	✅ Full replacement	Turnkey hardware + software, days vs. months setup
Multi-vendor / mixed bioreactor estate	✅ Strong replacement	OPC-UA native, no Sartorius-only lock-in
Lab-to-pilot upstream (150 mL–50 L)	✅ Full replacement	~40 services, lower TCO, perpetual licensing
Stainless-steel pilot/production (PLC + OPC-UA)	✅ Strong replacement (new)	Industrial-PC deployment, reuse existing PLCs
Biostat B-DCU benchtop modernization	✅ Strong replacement	Browser-based, no DCU-tower / Windows dependency
Parallel fermentation (multi-vessel)	✅ Strong replacement	Plug-and-play parallel, auto-generated P&ID per process
End-to-end USP + DSP + filling	⚠️ Partial / complementary	QB Control for upstream; Sartorius DSP via OPC-UA bridge
GMP production (>200 L single-use, multi-train)	❌ Not a replacement	Biostat STR + BioBrain is the industry standard
Sub-150 mL high-throughput screening	❌ Not a replacement	ambr 15 / ambr 250 are the native fit

2. Platform Philosophy

Fundamental Architecture Difference

Dimension	Sartorius BioBrain	QB Control
Product Category	Hardware-anchored automation + SCADA ecosystem	SCADA-class browser-based platform (hardware + software)
Design Philosophy	Vertical integration, hardware-first	Co-engineered, modular-first, vendor-neutral
Target Scale	Screening (sub-15 mL) through GMP production (2000 L)	Lab-to-pilot (150 mL – 50 L benchtop); stainless-steel pilot/production via PLC + OPC-UA
Approach to Hardware	Sartorius bioreactors + PAT preferred; 3rd-party via OPC	Own modular hardware (QB Modules) + open sensors; or existing PLCs (Wago/Siemens/Beckhoff)
Software Delivery	Windows-based SCADA client + SQL back-end	Browser-based (any device, any OS)
Deployment Host	Industrial PLC + Windows servers/clients	QB Edge for benchtop or standard industrial PC for PLC-based stainless steel
Configuration Model	PLC/SCADA configuration + ISA-88 batch (engineer-led)	Visual drag-and-drop recipe designer (no coding)
Deployment Time	Months (engineered, validated)	Days (plug-and-play)
Vendor Strategy	Comprehensive single-vendor ecosystem	Open ecosystem (no lock-in)
GAMP Classification	Category 4/5 depending on customization	Category 4 (configurable software)

The Over-Buy Problem

Sartorius BioBrain assumes the client benefits from a single accountable vendor across the entire bioprocess — screening, upstream, PAT, downstream, and fill-finish — and that the customer’s workflow justifies enterprise PLC/SCADA architecture, a global validated-supplier relationship, and recurring lifecycle agreements. For an integrated GMP manufacturer, that assumption is correct and genuinely valuable. But it creates significant over-buy for:

R&D laboratories running 150 mL–10 L bioreactors
Process-development teams that need agility more than ecosystem breadth
Pilot-scale facilities with 10–50 L vessels
Stainless-steel pilot cells that have a PLC but no need for the full Sartorius stack
Multi-vendor sites that deliberately mix bioreactor and sensor brands
Academic research labs and CDMOs running varied client campaigns

Buying the full end-to-end ecosystem to run a six-vessel development lab means paying for screening, downstream, and fill-finish capability that the lab will never use. QB Control is purpose-built for these upstream lab/pilot scenarios — and it now scales the stainless-steel pilot/production path through industrial-PC deployment and OPC-UA/PLC integration, without inheriting ecosystem cost, lock-in, or validation burden. Where the customer genuinely needs the full ecosystem, Sartorius is the better answer, and the two can coexist over OPC-UA.

3. Architecture & Hardware

Controller & Hardware Architecture

Component	Sartorius BioBrain	QB Control
Central Controller / Host	Industrial PLC + Windows SCADA servers/clients	QB Edge (runs QB Control locally) or industrial PC for PLC-based stainless-steel systems
I/O Architecture	Industrial field I/O + Profinet/Profibus	Power-over-Ethernet (one cable = power + data per module); or PLC I/O (Wago/Siemens/Beckhoff) via OPC-UA
SCADA Software	Windows-based SCADA client	Browser-based (any OS: Windows, Mac, Linux)
Device Discovery	Engineered configuration + commissioning	Auto-discovery (Plug & Play) — device appears in QB Control automatically
Workstation Requirement	Windows workstations + SCADA client install	Any device with a browser (Chrome, Firefox, Edge, Safari)
Form Factor	Bioreactor towers + control cabinets + server room	Bench-top modules; or industrial PC + existing PLC cabinet
Power Architecture	Cabinet power supplies + UPS	PoE — single cable per module, no external power supplies (benchtop)
Wiring	Traditional field wiring + marshalling	Single Ethernet cable per module (benchtop); PLC reuse for stainless steel
Data Storage	SQL database historian, configurable retention	Local store + optional cloud backup, 1+ year retention configurable

Sartorius Bioreactor Portfolio vs. QB Modules

Sartorius’s hardware breadth is its defining strength. BioBrain is the modern automation endpoint for Sartorius’s single-use upstream line, while the broader ecosystem spans screening through fill-finish:

Sartorius Hardware	Scale / Role	BioBrain Integration
Biostat STR	12.5 L–2000 L single-use stirred tank (GMP)	Native (primary automation platform)
Biostat RM	50 L–500 L single-use rocking	Native
Biostat B-DCU	2 L–10 L benchtop multi-use	Legacy DCU tower (not native BioBrain)
ambr 15 / ambr 250	10–250 mL parallel micro/mini-bioreactors	Proprietary ambr software (separate from BioBrain)
BioPAT (Trace, ViaMass, Spectro)	PAT analytics & automated sampling	Modbus / OPC-UA
Sartoflow / Flexact / AliquoT	Downstream TFF, DSP, single-use filling	BioBrain-coordinated

QB Control takes the opposite approach: it ships its own modular benchtop hardware and connects open instruments, but deliberately limits itself to upstream control from 150 mL through pilot scale (and stainless-steel pilot/production via PLC).

Function	Sartorius Approach	QB Control Approach
Pumps	Integrated in Biostat / Flexact skids	QB Pump (peristaltic, centrifugal, syringe) — native; SmartPump (OPC) for 3rd-party
Sensors	BioPAT + native probe ports	QB Multisensor — connects Hamilton/Mettler Toledo probes natively
Agitation	Integrated in Biostat drives	QB Agitator, QB Multiagitator (2 or 6 vessels) — native
Temperature	Integrated TCU / jacket control	QB Thermo (heating/cooling, heating mats) — native
Gas Flow	Integrated MFC banks	QB Gasflow (up to 2 gas streams) — native
Valves	Integrated single-use manifolds	QB Pinch Valve, QB Selector Valve (24 positions), three-way — native
Scales	Integrated load cells	QB Multiscale (up to 6 scales via RS232) — native
Foam Detection	Probe-based	QB Foam Sensor — optical, patent-pending, non-contact
Lighting	Not a focus	QB Light (up to 6 LED outputs for photobioreactors)
Pressure	Single-use transducers	QB Pressure Sensor (up to 2 single-use IBP transducers)

Key Hardware Advantage: QB Control

No control cabinets, no server room for benchtop deployments — bench-top modules with auto-discovery
PoE eliminates separate power infrastructure
Open sensors — use Hamilton, Mettler Toledo, Levitronix at market price (no ecosystem markup)
Mix any bioreactor brand — Sartorius, Eppendorf, Applikon, Infors, or custom, via OPC-UA
New: for stainless-steel systems with existing PLCs, QB Control deploys on an industrial PC and integrates over OPC-UA — reusing field hardware instead of replacing it

Key Hardware Advantage: Sartorius

Unmatched scale ceiling — single-use Biostat STR to 2000 L, GMP-proven
End-to-end hardware — upstream, PAT, downstream, and filling from one validated supplier
Sub-150 mL screening — ambr 15 / ambr 250 high-throughput micro/mini-bioreactors
Global validated-supplier network and consumables supply chain

4. Parallel Processing

Side-by-Side Comparison

Capability	Sartorius BioBrain	QB Control
Max Parallel Vessels	Multi-unit SCADA across many process units; ambr adds 24–48 parallel micro/mini-vessels	Multiple parallel processes (license-dependent); QB Multiagitator supports 6 vessels per module; multi-instance services per process
Parallel Architecture	Each unit configured in the SCADA hierarchy; ambr is a separate software domain	Each bioreactor = independent Process with own P&ID, alarms, recipes, batch recording
Shared Resource Management	SCADA-level arbitration for shared utilities	Process-level resource allocation; conflict blockade prevents collisions
Independent Recipes Per Vessel	Yes — per-unit recipes	Yes — different recipes per process; parallel and sequential batch execution
Sequential Campaign Queuing	Recipe scheduling per unit	Sequential batch execution with Pending queue + per-batch auto-stop (new)
Unified Data View	SQL historian across units	QB Graphs (per-process live + history), Reports (per-batch)
Cross-Batch Comparison	SQL historian queries + batch recall	QB Graphs multi-parameter overlay + CSV export
High-Throughput Screening	ambr 15 / ambr 250 (24–48 parallel) — best-in-class	Not supported below 150 mL
Campaign Management	SCADA recipe library + scheduling	Recipe Executions Board with full batch lifecycle

QB Control’s Parallel Processing Model

QB Control implements parallel processing through its System → Process → Batch hierarchy:

System defines the physical resources (devices, services, equipment, media)
Multiple Processes can be defined within a system, each with its own auto-generated P&ID, alarm configuration, recipe assignment, batch recording, and reports
Multi-instance services allow the same service type to be instantiated across multiple processes
Parallel Recipe Execution — multiple recipes run simultaneously across different processes
Sequential execution (new) — batches can be queued with a Pending status and chained with auto-stop conditions, enabling unattended campaign sequencing
Process-level isolation — each process operates independently with its own control loop and its own per-process emergency stop (P-Stop)

Where QB Control Excels in Parallel Processing

No system integrator needed to set up parallel operations
Visual P&ID per process — auto-generated from configuration, not manually drawn; preserved and copied forward on versioning
Process & recipe Import/Export with device mapping — replicate a proven setup to new bioreactors and remap devices to the target system instantly
Multi-user concurrent access — different operators monitor/control different processes simultaneously from different devices
Lower incremental cost — adding a parallel bioreactor = adding QB Modules + license expansion (not buying new towers, workstations, or SI engagement)
Vendor-mixed parallel — run a Sartorius, an Eppendorf, and a custom vessel side-by-side in one platform

Where Sartorius Excels in Parallel Processing

High-throughput screening — ambr 15 / ambr 250 deliver 24–48 parallel vessels for DoE, strain selection, and media optimization that QB Control cannot match
Production-scale multi-train — multiple GMP Biostat STR units coordinated under one validated SCADA
Mature SQL historian for cross-batch analytics at enterprise scale
Integrated PAT across parallel runs — BioPAT sampling and analytics shared across vessels

5. Multi-Vendor Integration

Protocol Support Comparison

Protocol	Sartorius BioBrain	QB Control
OPC UA	Native (server/client) — primary path to 3rd-party DCS/MES	Native — primary path for PLC/stainless-steel integration; dedicated OPC UA Connector module with configurable mappings
Modbus	Supported (PAT / sensors)	Supported (TCP and RTU)
MQTT	Not native (requires gateway)	Native — IoT real-time streaming
REST API	Limited / custom	Native — modern web integrations
SQL (JDBC/ODBC)	Native historian; external access via DB	Native — direct database access
LDAP/Active Directory	Supported via Windows integration	Native — SSO with corporate credentials, configurable search scope/timeout/pagination
MTP (Module Type Package)	NAMUR-aligned via Sartorius tooling	Supported (new) — plug-and-produce integration + MTP-oriented signal presentation in Graphs
PROFIBUS / PROFINET	Native (industrial backbone)	Profibus supported; PLC protocols (Wago/Siemens/Beckhoff)
SMTP (email)	Via SCADA configuration	Native — notification dispatch with SMTP config + delivery logs
Secured external communication	Via DMZ/gateways	Supported — encrypted, protected external traffic

Sensor & Bioreactor Vendor Support

Vendor	Sartorius BioBrain	QB Control
Hamilton	Supported (often via adapters)	Native — Arc sensors via QB Multisensor (DO, pH, conductivity, OD, CO₂, ORP); two-point / zero-point / slope calibration
Mettler Toledo	Supported (often via adapters)	Native — ISM/Modbus sensors via QB Multisensor
Levitronix	Custom integration	Native — flow meters via QB Multisensor
Sartorius BioPAT	Native (best-in-class)	Via OPC-UA (not native)
3rd-party bioreactors (Eppendorf, Applikon, Infors)	Possible via OPC, vendor support needed	Native via OPC-UA — mix any brand

Integration Philosophy Difference

Sartorius: “We provide the entire bioprocess stack — bioreactors, PAT, downstream, filling, and the automation/SCADA layer to coordinate it. Our integrations are deepest and most seamless within our own ecosystem; third-party equipment connects via OPC-UA but is not the design center. The reward is a single accountable vendor with one validation relationship across the whole workflow.”

QB Control: “We provide both the control platform AND modular hardware. Our modules natively connect Hamilton, Mettler Toledo, and Levitronix sensors, and any bioreactor brand via OPC-UA. For anything else, we offer Modbus, MQTT, REST API, SQL, and MTP — and we deploy on your existing PLCs for stainless-steel systems. No ecosystem lock-in, no Sartorius-only pathway.”

QB Control’s Integration Advantage

Vendor neutrality by design — mix Sartorius, Eppendorf, Applikon, Infors, or custom bioreactors in one platform without re-qualifying a single ecosystem
Native sensor support — Hamilton and Mettler Toledo probes connect directly to QB Multisensor via Modbus RS485, no adapters
Modern protocols — MQTT, REST API, SQL are native
OPC UA Connector — a dedicated module bridges OPC-UA equipment (including Sartorius BioPAT) into QB Control with configurable mappings — the path for PLC-based stainless-steel systems
MTP support (new) — plug-and-produce modular integration
Auto-discovery vs. manual commissioning

Sartorius’s Integration Advantage

Deepest native integration within its own ecosystem — Biostat, BioPAT, Sartoflow, Flexact, AliquoT designed to work together
Single validation relationship across upstream, PAT, and downstream
Mature industrial protocol support for plant-scale integration (PROFINET, PROFIBUS)
Plant-wide integration — connects to MES, ERP, LIMS at enterprise level
Proven at production scale in regulated GMP facilities worldwide

6. Software Module Comparison

Module-by-Module Mapping

QB Control ships 18 software modules, accessed through the Portal. The two additions since the previous comparison are Remote Access and Health Monitoring. Note that Sartorius distributes equivalent capability across several distinct software products (the BioBrain automation/SCADA layer, ambr software, BioPAT data management, and downstream control), whereas QB Control consolidates upstream control into one interface.

Capability Area	Sartorius BioBrain Component	QB Control Module	Comparison
Device Management	SCADA device configuration + commissioning	Inventory (auto-discovery, device status, configuration import/export, licensing)	QB simpler & faster
System Configuration	SCADA engineering tools	System (visual resource allocation, search, bulk add/remove, history to CSV)	QB no-code
Process Configuration	Per-unit recipe/parameter configuration	Process (visual binding, versioning, duplicate process, live connection status, guided import/export)	QB faster
Process Visualization	SCADA mimics (engineered)	P&ID (auto-generated, drag-and-drop, recipe execution from diagram, P-Stop/E-Stop)	QB auto-generates; Sartorius manual design
Batch Management	ISA-88 recipe execution	Recipe (Designer / Batch / Executions Boards)	QB visual designer with Services; Sartorius more formally ISA-88
Services Catalog	No equivalent (engineered per project)	Services (~40 templates across 10 categories, load & execute in minutes)	QB unique advantage
Service Profiles	No equivalent	Service Profiles (reusable grouped/atomic parameter templates, portable import/export)	QB unique advantage
Alarm Management	ISA-18.2 alarm handling	Alarms (ISA-18.2 conformance, watchlist, in-app global notifications)	Comparable (both ISA-18.2)
Data Visualization	SQL historian + trending	Graphs (live + history, multi-axis, annotations, MTP signals, export)	Sartorius more powerful historian; QB adequate for scale
Reporting	Batch reports + MES integration	Reports (automated + manual, PDF/DOCX, recipe-execution & service-history sections)	Sartorius enterprise-grade; QB sufficient for lab/pilot
Batch Tracking	SCADA batch historian	Runs (per-process, batch ID, user tracking, report linkage)	Both adequate
Calibration	External / probe tools	Calibration (status tracking, Next Due Dates, Hamilton/pump methods, device-type-aware history)	QB integrated
Audit Trail	SQL audit logging (21 CFR Part 11)	Audit Trail (21 CFR Part 11 conformance, cross-module, exportable CSV)	Both strong
Access Control	Windows-based RBAC	Users & Roles (RBAC, 18 permission groups, LDAP/AD)	QB more modern (web-based)
Notifications	SCADA alerting	Notifications (in-app center, email/SMTP, per-user preferences, recipe-step alerts, logs)	QB richer out-of-box
Backup	SQL backup utilities	Backup, Export & Archive (scheduled/manual wizards, one-click restore, integrity verification)	Comparable
License Management	Per-unit / per-user SCADA licensing	License (feature/device/system/time-based, online/offline, host-bound, license guards)	QB more flexible
Remote Access	SCADA remote client (Windows)	Remote Access (secure VPN, QR-code setup, phone/tablet/PC, role-based) — new	QB simpler, multi-device
Health Monitoring	Diagnostics across tools	Health Monitoring (system health dashboard, per-module status, drill-down) — new	QB consolidated, always-on
High-Throughput Screening	ambr software (24–48 parallel)	❌ Not available	Sartorius wins
PAT / Analytics	BioPAT (Trace, ViaMass, Spectro)	❌ Not native (OPC-UA bridge)	Sartorius wins
Downstream Control (DSP)	Sartoflow / Flexact	❌ Not available (upstream only)	Sartorius wins
Fill-Finish	AliquoT	❌ Not available	Sartorius wins
Edge Computing	—	QB Edge (runs QB Control locally)	Different approach

7. Services Catalog & Rapid Deployment

QB Control’s Services Catalog — A Game-Changing Differentiator

One of QB Control’s most powerful advantages over Sartorius BioBrain is the Services Catalog — a library of pre-built, parameterized service templates that can be loaded and executed within minutes. A Service is a pre-defined control action (the equivalent of a control loop) that directly commands hardware. Services come in two types:

Autocomplete Services — execute a discrete task and close automatically (e.g., Transfer Volume by Pump, Add Gas Volume by MFC)
Continuous Services — run until explicitly stopped (e.g., Set Agitator Speed, Temperature Control by TCU, pH Control by Base & CO₂)

Sartorius BioBrain has no equivalent off-the-shelf upstream services library; control strategies are configured and engineered per project as part of the broader ecosystem deployment.

Services Catalog by Category

QB Control ships with ~40 pre-built service templates across 10 functional categories out of the box, with QB Filtration adding a tangential-flow filtration set (recently expanded). This covers every core upstream bioprocess control need:

Category	Example Services	Count	Types
pH Control	pH Control by Base & CO₂, by Base & Acid, by One Pump, One Pump PID, pH PID Control	6	Continuous
Temperature Control	by TCU, by Heating Mat, by Steam & Water, Split Temp, Set Circulator Temp, Set Heating Mat Power	6	Continuous
Pump & Feed	Feed, Autosubstrate, Set Pump Flow Rate, Set Centrifugal Pump RPM, Transfer Volume/Bolus, Gravimetric Feeding	9	Continuous + Autocomplete
Gas Control	O₂ Control, Advanced O₂ Control, Set MFC Flow, Set Sparger Mass Flow	4	Continuous
Gas Volume Delivery	Set Sparger Volume & Mass Flow	1	Autocomplete
Sampling	Automated Sampling, Sample by Syringe Pump, Sampler Cleaning	3	Continuous + Autocomplete
Stirring & Agitation	Stirring, Set Agitator Speed	2	Continuous
Foam Control	Foam Control, Foam Control by Antifoam Reagent	2	Continuous
Valve Control	Set Selector Valve Position, Set Valve Position	2	Continuous
LED & Light	LED Control, LED Control Scheduler	2	Continuous
Core catalog (out of the box)		~40	across 10 categories
QB Filtration add-on	Filtervig Control, Concentration Factor Logic, NWP Calculator, Breakthrough Detection, plus six new tangential-flow services	expanded	Continuous + Autocomplete

Service Profiles — Reusable Parameter Templates

QB Control’s Service Profiles (Settings → Service Profiles) let users save standardized parameter configurations as reusable templates. QB Control adds grouped and atomic-style configuration models, structured profile cards (e.g., PID Controller Tuning, Temperature Ramp, Operating Limits), and portable export/import to transfer complete profile sets between templates or environments. Profile-driven values are labeled in execution review for traceability.

How Services Transform Experiment Deployment

Workflow Step	Sartorius BioBrain Approach	QB Control with Services Catalog
Define control strategy	Configure/engineer in the SCADA/automation layer	Select service template from catalog
Set parameters	Enter values in SCADA configuration (trained engineer)	Load a saved Service Profile or enter values in a visual form
Change control logic	Reconfigure + re-validate	Swap service template — minutes, not days
Deploy to process	Commission, test, validate	Add service to process; it appears in Recipe Designer — minutes
Try a different strategy	New engineering engagement	Select a different service / apply a different profile — instant

Deployment Timeline Comparison

Phase	Sartorius BioBrain	QB Control
Sales & scoping	Enterprise quotation, ecosystem scoping	Transparent reference pricing
Hardware procurement	Bioreactors + automation + servers (weeks–months)	QB Edge + QB Modules (standard BOM)
Setup & configuration	Engineered SCADA/PLC configuration	Customer self-setup, plug-and-play
Recipe development	Engineer-led recipe configuration	Visual no-code recipe build
Validation (IQ/OQ/PQ)	Full ecosystem qualification	Lightweight; audit trail pre-built
Time to first run	Months	Days to a few weeks

This is a capability the BioBrain ecosystem does not match at lab/pilot scale. Where Sartorius shines is the opposite end: a fully validated, end-to-end GMP system delivered as one accountable package — worth the longer timeline when the workflow demands it.

8. Recipe Engine

Overview

The Recipe Module is the core automation engine of QB Control. It translates biotechnological protocols into executable digital workflows by combining logic blocks and Services (hardware actions), through three integrated boards: Designer Board (create/edit), Batch Board (configure/execute), and Executions Board (monitor history). Sartorius BioBrain uses an ISA-88-aligned recipe model configured in its automation/SCADA layer — formally rigorous and production-proven, but engineer-led rather than no-code.

8.1 Designer Board & the Unified Block Library

The Designer Board is a visual, drag-and-drop workspace for building process logic as a connected flow. QB Control consolidates the previous per-service blocks into a unified block library with built-in grouping, descriptions, tooltips, and embedded in-app guidance:

Block	Category	Function
Start Service	Service Control	Single configurable block (replaces many per-service start blocks); pick the service at configuration; supports Autocomplete (run-to-completion) and Continuous (keep running)
Stop Service	Service Control	Explicitly stop a continuous service later in the flow
Update Service Inputs	Service Control	Change service input values mid-execution (startup vs. runtime-adjustable inputs kept separate)
Service Profile support	Service Control	Start/Update blocks accept preset profile configurations; profile values labeled in execution review
Manual Operation	Operations	Pause for operator-driven action where supervised intervention is required
Variable / Update Variables	Variables	Declare named values (boolean, text, number, time); update with increase / decrease / multiply / divide
Timer	Timing	Shared timer control with start / stop / pause / resume modes
Set Valve State	Equipment commands	Command valve positions directly as part of the sequence
Conditional	Logic & flow	Evaluate real-time variables with AND / OR expressions
Counter	Logic & flow	Loop control with iteration count
PID	Logic & flow	Inline PID-oriented control block
Polygon	Logic & flow	Piecewise-linear mapping (X→Y) for ramps and profiles
Split / Merge	Logic & flow	Fork into parallel paths and join them back together
Wait / Wait Until / Start / Stop / End	Standard	Time-based pause, condition-based pause, and execution control

Authoring productivity: copy/paste of blocks, signal filtering for cleaner input selection, undo/redo, diagram export (image), and recipe import/export across installations. The designer flags inactive recipes that should not be started as-is.

Recipe state lifecycle: Draft → Verified → Validated → Hold → Archived. Critically, only Verified or Validated recipes can run in batches — not just Validated — which streamlines development without weakening control.

8.2 Batch Board

Create batches for processes and assign single or multiple recipes per batch
Real-time view to monitor and control execution (stop, pause, resume)
Sequential batch execution with Pending status for queued batches and auto-stop configuration per batch
Edit parameters from the execution board where permitted — no round-trip to the designer mid-run
Step execution counts and live recipe status updates

8.3 Executions Board

List of executed batches with start/finish time, status, and configuration
Statuses: During Execution, Paused, Hold, Pending, Completed, Failed, Aborted
Filter by System, Process, Status; export list to CSV; export recipe flow to PNG
Direct links to the live view of currently executing recipes

8.4 Validation & Safety

The Validator — visual workspace for verifying recipe logic before execution
Automated pre-start validations prevent batch collisions, unauthorized recipe starts, and execution on disconnected hardware
Mandatory pre-execution checklist forces operators to verify critical lab elements (tubing integrity, media preparation) before start
License guard — creating, duplicating, or importing recipes is blocked when the recipe license limit is reached
Emergency integration — runs hold or abort safely when a P-Stop or global E-Stop is active

8.5 Recipe Engine vs. Sartorius BioBrain — Detailed Comparison

Capability	Sartorius BioBrain	QB Control Recipe Engine
Workflow design	ISA-88 procedural model (trained engineer)	Visual drag-and-drop Designer Board (no coding)
Parallel execution	Unit-level coordination	Split/Merge blocks for parallel paths
Sequential campaigns	Recipe scheduling per unit	Sequential batches with Pending queue + auto-stop
Conditional logic	SCADA scripting / SFC	Conditional blocks with AND/OR on real-time data
Variables & math	SCADA scripting	Variable / Update Variables (increase/decrease/multiply/divide)
Timers	Phase logic	Timer block (start/stop/pause/resume)
Human-in-the-loop	Manual phase prompts	Manual Operation block
Execution monitoring	SCADA operator interface	Batch Board with real-time, color-coded status
Recipe versioning	Recipe library + approvals	Draft → Verified → Validated → Hold → Archived
Pre-execution safety	Operator checklist (configurable)	Mandatory checklist + Validator (system-enforced)
Ramp/profile control	Configured profiles	Polygon block + service ramp parameters
Diagram export	Not standard	Export as image / PNG for compliance docs
ISA-88 formal compliance	Best-in-class, production-proven	Follows batch concepts; not formally certified
Time to create recipe	Hours to days (engineer-led)	Minutes to hours (visual, no-code)

9. Regulatory Compliance

Standard	Sartorius BioBrain	QB Control	Notes
FDA 21 CFR Part 11	✅ Full compliance	⚠️ Partial conformance	Sartorius: full (with e-sigs). QB: electronic records, audit trails, access control, user management today — electronic signatures not yet covered
EU Annex 11	✅ Full compliance	✅ Compliance support	Both provide computerized-system validation capabilities
GAMP 5	Category 4/5 (configurable to custom)	Category 4 (configurable)	QB Control has a low validation burden — no custom code to validate
ISA-18.2 (Alarms)	✅ Full compliance	✅ Conformance	Both support suppressed, out-of-service, acknowledgement workflows
ISA-88 (Batch)	✅ Full compliance (production-proven)	⚠️ Follows batch concepts; not formally ISA-88 certified	Sartorius stronger for formal ISA-88 compliance
ALCOA+ (Data Integrity)	✅ Full implementation	✅ Full implementation	Both provide ALCOA+ data integrity
Electronic Signatures	✅ Built-in (production-ready)	◐ On roadmap (Q3 2026 — not in current version)	Sartorius leads; QB planned
Audit Trail	✅ Immutable, SQL-backed	✅ Immutable, exportable (CSV), cross-module, searchable	Both comprehensive
Safe Position Logic (GMP)	Via interlock engineering	✅ Built-in — define safe actuator states after restart/power cycle	QB has a dedicated, configurable feature
CE Marking	System-level	✅ Per QB Module (EMC + Low Voltage Directive)	Each module ships its own Declaration of Conformity
Validated supplier network	✅ Global, GMP-certified manufacturer	Growing	Sartorius advantage at production scale

Compliance Value for QB Control

GAMP 5 Category 4 is a significant differentiator at lab/pilot scale. As configurable software with no custom code to validate, QB Control means reduced validation scope, standardized test scripts, lower CSV cost, simpler change management (configuration changes, not code changes), and faster time to GMP-ready operation (weeks vs. months for the upstream control layer) — whereas heavily customized enterprise ecosystem deployments can trend toward Category 5 complexity, with correspondingly heavier validation.

Honest Compliance Caveat

QB Control’s 21 CFR Part 11 conformance is partial: it delivers electronic records, audit trails, access control, and user management today, but electronic signatures are not yet implemented (roadmapped for Q3 2026). For regulated batch release that requires digital signatures today, Sartorius BioBrain is the safer choice — it has mature, production-ready 21 CFR Part 11 with electronic signatures and a validated-supplier relationship. Do not represent QB Control as fully 21 CFR Part 11 compliant.

Note: Sartorius pricing is enterprise quote-based and includes its end-to-end value (validated supplier network, ecosystem integration, GMP-scale capability). The comparison above isolates the upstream control layer for a lab/pilot workflow; it is not a like-for-like for a full GMP production or end-to-end USP+DSP+fill deployment, where Sartorius delivers capability QB Control does not offer.

Licensing Model Comparison

Aspect	Sartorius BioBrain	QB Control
Model	Per-unit / per-user SCADA + mandatory annual agreement	Perpetual license — feature-, device-, system/process-, and time-based dimensions
License Type	Mandatory annual renewal (no perpetual SCADA option)	Perpetual — buy once; no recurring license fees
Support	Bundled lifecycle agreement	Paid separately — tiered (Basic, Standard, Premium), client’s choice
Enforcement	Per-unit / per-user entitlement	Software license bound to the deployment host; license-aware UI and guards surface limits
Lock-In	Tied to Sartorius ecosystem	Not tied to a specific hardware vendor
Hardware Dependency	Sartorius bioreactors + Windows infrastructure	Any browser-capable device; QB Edge or industrial PC

Licensing Model — Key Client Value

No mandatory annual software fees — the perpetual license does not expire, eliminating Sartorius’s recurring Software & Lifecycle Agreement burden
Paid support is optional and tiered — no forced bundling
Predictable budgeting — one-time license + optional support
No “license hostage” risk — perpetual model means a lapsed contract never locks you out of your own system
No ecosystem premium — choose bioreactors and sensors on price and performance, not vendor lock-in

12. What QB Control Can Replace

Full Replacement Scenarios

1. Lab-Scale Upstream Control (150 mL–10 L) — BioBrain on benchtop/single-use vessels → QB Edge + QB Modules. Value: large cost reduction, days vs. months setup, no SI, browser-based access.

2. Biostat B-DCU Benchtop Modernization — Legacy DCU tower / Windows dependency → QB Control browser-based platform. Value: identical upstream control (temperature, DO, pH, aeration) at a fraction of the cost, modern data logging, no DCU-tower dependency.

3. Parallel Small-Scale Fermentation — Multi-unit upstream SCADA → QB Control multi-process with QB Multiagitator. Value: plug-and-play parallel, auto-generated P&ID per process, sequential auto-stop campaigns, lower incremental cost per vessel.

4. Stainless-Steel Pilot Cells with Existing PLCs (new) — Engineered automation layer → QB Control on an industrial PC integrating the PLC via OPC-UA + the OPC UA Connector. Value: reuse field hardware, no ecosystem license, no SI re-engineering.

5. Multi-Vendor Upstream Sites — Sartorius-centric SCADA → QB Control vendor-neutral platform. Value: mix Sartorius, Eppendorf, Applikon, Infors, and custom vessels in one interface.

6. pH/DO/Temperature Control Loops — BioBrain PID loops → QB Multisensor (Hamilton/MT) + QB Gasflow + QB Thermo + services. Value: native sensor integration, no adapters.

7. Process Development & Tech-Transfer Replication — Engineered reconfiguration → QB Control process import/export + device mapping. Value: change setups in minutes, run different configs on parallel vessels.

Partial Replacement Scenarios

8. End-to-End USP + DSP Facility — QB Control handles upstream; Sartorius DSP (Sartoflow, Flexact) and fill (AliquoT) retained and bridged via OPC-UA. Value: decouples upstream from downstream, allowing future DSP flexibility, while keeping Sartorius where it leads.

9. Small-Scale GMP Production — QB Control provides partial 21 CFR Part 11 conformance (records, audit trails, RBAC, data integrity; e-signatures on roadmap). Value: lower validation burden (GAMP 5 Category 4), but may require additional qualification documentation and an e-signature bridge until Q3 2026.

What QB Control Cannot Replace

Sartorius System	Reason	Recommendation
ambr 15 / ambr 250	Sub-150 mL high-throughput screening; QB has no HTS platform	Keep ambr for screening; QB Control for scale-up
Biostat STR (production, 500–2000 L)	GMP single-use production scale	Use Biostat STR + BioBrain
Sartoflow / Flexact (DSP)	Downstream automation; QB upstream-only	Bridge via OPC-UA, retain Sartorius DSP
AliquoT (fill-finish)	Single-use filling; QB has no filling platform	Not applicable for QB upstream labs
BioPAT (PAT analytics)	Native automated sampling + analytics	Bridge via OPC-UA; not native in QB

13. Where QB Control Creates Superior Value

13.1 Value Summary

Each pillar is detailed in the section noted; in brief, QB Control delivers:

Vendor independence — mix any bioreactor and sensor brand (Sartorius, Eppendorf, Applikon, Infors, or custom) via OPC-UA, with open sensors and consumables at market price and no ecosystem re-qualification (§5).
Lower TCO, no annual surprises — ~5× lower 5-year cost for a 4-bioreactor upstream lab, a perpetual license with no mandatory annual software & lifecycle agreement, and no system-integrator or dedicated-workstation cost (§10).
Unified single platform — one browser-based interface for all upstream control, with one data schema, one security model, and one operator training program — no context-switching across BioBrain, ambr software, BioPAT, and downstream tools (§7).
~40 pre-built services — load and execute control strategies in minutes, swap a strategy on demand via Service Profiles, where Sartorius engineers each strategy per project (§7).
Modern, open integration — native OPC-UA, REST, MQTT, SQL, MTP, LDAP/AD, and secure remote access with QR-code setup (§5).
Right-sized safety & compliance — P-Stop/E-Stop, Safe Position Logic, a mandatory pre-execution checklist + Validator, and GAMP 5 Category 4 simplicity (§8, §9).

14. Gaps & Limitations

Sartorius Capabilities Not Available in QB Control

Capability	Sartorius BioBrain	QB Control	Impact
GMP Production Scale (>200 L single-use)	Biostat STR to 2000 L	Lab-to-pilot/early-production focus	High
High-Throughput Screening (sub-150 mL)	ambr 15 / ambr 250 (24–48 parallel)	Not available (150 mL minimum)	High
End-to-End Ecosystem (USP+DSP+fill)	Integrated portfolio	Upstream only	High
PAT / Spectral Analytics	BioPAT (Trace, ViaMass, Spectro)	Not native (OPC-UA bridge)	Medium–High
Downstream Processing (DSP)	Sartoflow / Flexact	Not available	High for integrated facilities
Fill-Finish	AliquoT	Not available	High for integrated facilities
Electronic Signatures	Built-in (production-ready)	On roadmap (Q3 2026)	High for regulated production today
ISA-88 Full Compliance	Production-proven	Follows batch concepts; not formally certified	Medium
Validated Global Supplier Network	GMP-certified manufacturer, 50+ offices	Growing	Medium–High for large pharma
Enterprise Multi-Site SCADA	Multi-unit centralized console	Single-site (networkable)	Medium
MES Integration	Native EBR / MES path	REST API integration point	Medium

Honest Assessment of QB Control Limitations

Scale ceiling — optimized for lab-to-pilot and early stainless-steel production; large multi-train GMP production still favors Biostat STR + BioBrain
No sub-150 mL screening — QB Control’s minimum vessel scale is 150 mL; ambr-class high-throughput screening is not addressed
Upstream only — no downstream processing, no fill-finish; integrated facilities must retain Sartorius (or third parties) and bridge via OPC-UA
No native PAT — automated sampling and spectral analytics are not embedded (BioPAT connects via OPC-UA)
No electronic signatures yet — 21 CFR Part 11 conformance is partial until the Q3 2026 release
ISA-88 not formally certified — QB Control follows batch concepts but is not formally certified, which some large pharma may require
Smaller installed base & support footprint — Sartorius’s global service network and decades of heritage are genuine advantages for multinational GMP operations
Liquid-handling upstream focus — QB Control does not address gas-phase, solid-phase, or complex hybrid processes

15. Migration & Replacement Scenarios

Scenario A: Greenfield Upstream Lab (No Existing Sartorius)

Recommendation: QB Control. New lab from scratch = no migration, no legacy. QB Control provides everything needed for lab/pilot upstream bioprocessing, ~80% cost savings vs. an equivalent Sartorius automation deployment, operational in days. Mix any bioreactor brand.

Scenario B: Biostat B-DCU Benchtop Lab Seeking Modernization

Recommendation: QB Control replacement. Replace legacy DCU-tower/Windows benchtop control with QB Control; gain browser-based access, modern data logging, and perpetual licensing. ROI typically recovered quickly through eliminated annual agreements.

Scenario C: Stainless-Steel Pilot Cell with an Existing PLC

Recommendation: QB Control on an industrial PC. Deploy QB Control on an industrial PC, integrate the existing PLC over OPC-UA via the OPC UA Connector, and keep the field instruments. Value: SCADA-class supervisory control and recipes without ecosystem price, lock-in, or SI re-engineering.

Scenario D: Multi-Vendor / Mixed Bioreactor Estate

Recommendation: QB Control as the unifying upstream platform. Where a site runs bioreactors from several vendors, QB Control consolidates them into one browser-based interface via OPC-UA — eliminating multiple SCADA instances and vendor-specific training. Keep any Sartorius vessels in the same view.

Scenario E: Integrated USP+DSP Facility (Complementary)

Recommendation: QB Control for upstream, Sartorius for downstream. QB Control handles fermentation/cell-culture upstream; Sartoflow/Flexact/AliquoT retained for DSP and fill-finish; bridge via OPC-UA. Value: upstream agility and lower cost without giving up Sartorius’s downstream leadership.

Scenario F: Academic / Research Institution

Recommendation: QB Control (full replacement for upstream). The full Sartorius ecosystem is prohibitively expensive for teaching/research; QB Control provides professional-grade upstream control at accessible cost, multi-student browser access (no per-seat/per-unit licensing), and modular hardware for curriculum flexibility. Keep ambr where high-throughput screening is part of the program.

16. Competitive Positioning Strategy

Positioning Statement

QB Control is not trying to out-ecosystem Sartorius. QB Control replaces the upstream control layer where the full Sartorius ecosystem is more than the workflow needs. Sartorius is the most complete bioprocessing portfolio in the industry — screening (ambr), single-use GMP upstream (Biostat STR to 2000 L), PAT (BioPAT), downstream (Sartoflow, Flexact), and fill-finish (AliquoT), all under one accountable, validated supplier. For an integrated GMP manufacturer, that is genuinely the right choice. But for lab-to-pilot upstream work, multi-vendor sites, and stainless-steel pilot cells that already have a PLC, buying the whole-airport ecosystem to run a six-vessel development lab is over-buy. QB Control delivers vendor-neutral upstream control for ~5× lower TCO, with a perpetual license, ~40 pre-built services, a visual no-code recipe engine, and deployment in days — and it coexists with Sartorius over OPC-UA where downstream or production scale is needed.

Key Sales Arguments

Sartorius Pain Point (at lab/pilot)	QB Control Advantage	Evidence
”Sartorius automation costs $300K+ for a 4-bioreactor lab”	Complete 4-bioreactor upstream lab for ~$60–85K	~5× lower 5-year TCO
”Mandatory annual Software & Lifecycle Agreement never stops”	Perpetual license — buy once, optional tiered support	No mandatory annual fees
”We’re locked into Sartorius hardware”	Mix any bioreactor/sensor brand via OPC-UA	Vendor-neutral by design
”We run BioBrain, ambr software, BioPAT, and DSP control separately”	One browser-based upstream platform	Single login, single training
”Changing an upstream control strategy is an engineering project”	Swap a service template in minutes	~40 pre-built services
”Setup took months with engineers on site”	Unbox, auto-discover, first experiment in days	Plug-and-play
”Validation of the full ecosystem was heavy”	GAMP 5 Cat. 4, validated in weeks (upstream layer)	50–75% validation reduction
”We need a Windows/SCADA workstation per operator”	Any browser on any device	Zero client infrastructure
”We want to reuse our stainless-steel PLCs”	Industrial-PC deployment + clean OPC-UA to your PLC	No rip-and-replace

When NOT to Position Against Sartorius BioBrain

Do NOT position QB Control as a replacement when the client needs:

GMP production at scale (>200 L single-use, multi-train) — Biostat STR + BioBrain is the industry standard
Sub-150 mL high-throughput screening — ambr 15 / ambr 250 are world-leading; QB Control has no HTS option
End-to-end bioprocess automation (USP + DSP + filling + PAT) with single-vendor validation — Sartorius’s integrated ecosystem is superior
Electronic signatures on an active IND today (before QB Control’s Q3 2026 release) — Sartorius is the safer choice
A validated global supplier relationship for multinational GMP manufacturing — Sartorius’s network and heritage win
BioPAT-centric workflows — automated sampling + Raman + biomass on integrated PAT

In these cases, position QB Control as complementary to Sartorius — handling lab/pilot upstream and multi-vendor flexibility while Sartorius handles screening, production scale, downstream, and fill-finish, connected over OPC-UA.

Overall: QB Control wins decisively for the target lab/pilot upstream market — usability, cost, recipe/services, and integration — while Sartorius wins at scale, screening, compliance maturity, and ecosystem breadth. With its unified recipe block library, sequential auto-stop campaigns, native MTP, secure remote access, Health Monitoring, vendor-neutral OPC-UA integration, and the industrial-PC deployment path, QB Control is the right-sized choice for upstream control at lab-to-pilot scale and stainless-steel pilot cells. Sartorius BioBrain remains the right choice for GMP production to 2000 L, ambr high-throughput screening, end-to-end USP+DSP+fill, and regulated workflows that require electronic signatures and a validated global supplier network today. The two coexist cleanly over OPC-UA.

Recent QB Control Enhancements (current release)

The current QB Control release adds the capabilities referenced in this comparison (reflecting the current QB Control release):

Batch scheduling — recurring (daily / weekly / interval) or one-time run schedules per batch, with a calendar view, named schedules, skip-on-conflict handling, and matching audit-trail records.
Recipe portability — a recipe can be reassigned to a different process, automatically remapping its devices and services so a proven design moves between similar lines instead of being rebuilt.
Equipment changes from the P&ID — lab equipment can be added directly in the P&ID editor (auto-creating the matching inventory and process records), with freeform note elements and anchor-point piping connections; lab equipment can also be added or removed on already-deployed processes without creating a new process version.
Embedded OPC UA server — the OPC UA Connector can now run its own embedded OPC UA server, letting external OPC UA clients (e.g., MES, historians) read from QB Control directly.
Expanded catalog — six additional tangential-flow (cross-flow) filtration services and six new lab-equipment types (including cooling chamber, filter cassette, hollow-fiber filter, and vials holder).
Operations & safety — an alarm watchdog reconciling alarm state against live equipment values every 30 seconds; calibration that reserves the device during calibration (blocking conflicting operations); Protect / Interlock faceplate safeguards; audit-trail events filtered to the active license; and license-aware controls shown with explanatory tooltips.
Usability — an in-app Help section with guided walkthroughs and searchable content across every module; search across inventory tables; and Health Monitoring showing system start time and uptime.
