Cheminert Model M6 and M50 liquid handling pumps are for precision handling of liquids and/or gases, producing a bidirectional pulseless flow with a range of 10 nL/min to 10 mL/min for the M6 and 50µL/min to 50 mL/min for the M50. A replacement for syringe pumps, they offer better performance and eliminate the need for refill cycles and syringe changes. Positive displacement pumps, they are self-priming and tolerant of gas in the fluid lines. There is no separate fill cycle, and the capacity is unlimited. RS-232 and RS-485 protocols are incorporated into the controller; USB interface requires an adapter.
