M6 Pump with stepper motor, no Controller, 100 µl, 100psi, 1/16'' Fitting, 1 mm Port, E3/P, SPHR/TF, SS body

The 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, so it's 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 basic 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 1 µl/min to 25 ml/min (35 ml/min intermittent). Standard pressure rating is 100 psi, but both models are also available in a high pressure version. Some high pressure configurations can hold pressures up to 1500 psi.
