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 100 nl/min to 25 ml/min (35 ml/min intermittent).

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