Cheminert Model M6 and M50 Positive-Displacement Pumps

The Cheminert Model M6 and M50 positive-displacement pumps produce a bi-directional pulseless flow with a range of over six orders of magnitude: 10 nL/min to 10 mL/min for the M6, and 50 µL/min to 50 mL/min for the M50. They are suitable as replacements for syringe pumps, and eliminate the need for refill cycles and syringe changes. RS-232 and RS-485 communication protocols are incorporated into the mircoprocessor-driven controller. The software package controls flowrates, 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 streamselection valve.
