M Series Syringe-Free Liquid Handling Pump

liquid handling pump

The patented Cheminert® M Series liquid handling pump is a syringe-free pump capable of delivering a bidirectional flow over six orders of magnitude. The M Series is a positive displacement pump, which means that it is self-priming and tolerant of any gas which may find its way into the fluid lines. There is no separate fill cycle, and the capacity is unlimited.

Two models are offered — the M6 with a flow range of 5 nl/min to 5 ml/min (10 ml/min intermittent), and the M50 with a range of 1 µl/min to 25 ml/min (35 ml/min intermittent).

USB and RS-485 communication protocols are incorporated into the microprocessor-driven controller. (USB requires an adapter.) The included software package controls flow rates, flow direction, and metered volumes.
