Earlier this year we introduced the concept of a novel air displacement pipette system powered by Disc Pump.
The new system—which we call the Volume Control Module (VCM)—leverages the exceptional pressure regulation of Disc Pump to deliver high precision fluidic dosing. This scheme can enable the creation of pipetting systems that are smaller, lighter & lower cost than the competition.
Over the last couple of months, our Research & Development team have been exploring this concept further in the lab, with the aim of characterising the performance of the system. The team demonstrated CVs of less than 1% over a wide pipetting range, from ~15µL to ~400µL.
Through the work, we also wanted to understand the key factors that impact pipetting performance, and to how to optimise the system. Our Application Note AN049 Pipetting with Disc Pump pdf1.16 MB provides a comprehensive technical overview of the system, and we have also put together a summary of Key Learnings below.
