Cheminert Model M6 and M50 liquid handling pumps

The Cheminert Model M6 and M50 liquid handling pumps are designed for precision handling of liquids and/or gases, and produce a bidirectional pulseless flow with a range over six orders of magnitude, from 10 nL/min to 10 mL/min for the M6 pump, and 50 µL/min to 50 mL/min for the M50 pump. Positive-displacement pumps offer much better performance than syringe pumps, which need refilling and syringe changes. They are self-priming and tolerant of any gas that may find its way into the fluid lines. There is no separate fill cycle, and the capacity is virtually unlimited. RS-232 and RS-485 communication protocols are incorporated into the microprocessor-driven controller. The included software package controls flowrates, flow direction and metered volumes.
