The Cost of Change: Flexibility and Plug and Play in Software Defined Liquid Handling
What a change actually costs in software-defined, plug-and-play liquid handling — across hardware, software, services, recipes and the licence, on QB Modules or the PLC you already own. Aligned with modular-automation standards (MTP, NAMUR, OPC UA) and industry initiatives like BioPhorum (BPOG), NIIMBL and O-PAS.

Delivered, Not Commanded: Ten Challenges in Bioreactor Feeding Control
A QB Systems whitepaper mapping ten places where fed-batch and perfusion feeding control breaks down — and what changes when the control layer is configurable while the run continues.
-
A custom perfusion bioreactor, built and proven in four days
How a 1 L custom perfusion bioreactor went from three gas valves to a thirteen-module process running eight closed control loops — verified over a twelve-hour unattended batch, in four days, with no control code and zero controller downloads.

A Second Life for Your Sartorius Bioreactors: Retrofitting with QB Control
QB Control retrofits your Sartorius Stedim bioreactors — keep the glass and steel you trust and replace only the aging, vendor-locked control layer with a modern, software-defined platform.
-
Years to market: why new bioprocess equipment is slow — and how to change the clock.
New instrument and bioprocess platforms take 4–7 years to reach market, and software is the hidden time sink. Here's how a software-defined, modular approach compresses new unit operations from years to months.

Architecture Matters: Integration Effort in Multi-Sensor Bioprocess Connectivity
Why the architecture you choose for connecting digital probes to OPC-UA and MQTT decides how much integration work you take on — a comparative, assumptions-based analysis of native PoE, transmitter-centric, and bus/converter approaches.
-
Don’t let vendor lock-in hold your lab hostage.
How to escape vendor lock-in and extend an existing SCADA system with a flexible, vendor-agnostic control platform that integrates equipment across OPC-UA, Modbus TCP and MQTT — keeping your lab open, not hostage.

Gravimetric feeding
Gravimetric feeding in QB Control — closing the feed loop on delivered mass with a load cell instead of pump revolutions. Setup, pulsation, PID tuning, instability, multi-flow and a one-hour rig, with real numbers.

Optimizing lab infrastructure through modularity, reusability, and parallel processing of software-defined system in labs of tomorrow.
Why lab infrastructure should be a reusable asset, not a sunk cost — using modularity, reusability and parallel processing in a software-defined system to run more science within the same footprint and headcount.
