Liquid Handling Pumps offer alternative to syringe pumps.
April 3, 2009 -
Designed to handle liquids and/or gases, Cheminert® Models M6 and M50 produce bidirectional pulseless flow with ranges of 10 nL/min to 10 mL/min and 50 µL/min to 50 mL/min, respectively. Positive displacement pumps are self-priming and tolerant of any gas that gets into fluid lines. Microprocessor-driven controller incorporates RS-232 and RS-485 communication protocols, while included software controls flow rates, flow direction, and metered volumes.

Cheminert® Liquid Handling Pumps
VICI Valco's Cheminert Model M6 and M50 Liquid Handling Pumps are a new generation of pumps for precision handling of liquids and/or gases, producing a bidirectional pulseless flow with a range of over six orders of magnitude (10 nL/min to 10 mL/min for the M6 Pump; 50 µL/min to 50 mL/min for the M50 Pump). An excellent replacement for syringe pumps, the Cheminert pumps offer better performance and eliminate the need for refill cycles and syringe changes.
The M6 and M50 are positive displacement pumps, which means they are 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.
RS-232 and RS-485 communication protocols are incorporated into the microprocessor-driven controller. (USB interface requires an adapter.) The included software package controls flow rates, flow direction and metered volumes. While the standard package includes software and instructions to run the M6 as a stand-alone unit, the software can also integrate a multiposition stream selection valve.
