LEE Ventus has developed a concept for an air displacement pipetting module enabled by our high-performance piezoelectric micropump, 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 concept can enable devices that are smaller, lighter and lower cost than conventional air displacement systems.
This application page describes a simple system architecture that enables the pump to be used in an air displacement regime, exploiting the high-precision pressure control and pulsation-free output of the pump to deliver exceptional performance. This scheme also enables aspiration and dispensing without the need for additional valving to reverse the flow.
