Cheminert® M Series Liquid Handling Pump

The patented 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, which means that it is 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 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).


Features:

• Continuous, bidirectional flow
• Two models:
  - M6: 5 nl/min to 5 ml/min
  - M50: 1 µl/min to 25 ml/min
• Mechanically simple
• No syringes to refill or break
• RS-232 and RS-485 control

Applications:

• Calibration source for mass spectroscopy
• Flow-based electrochemical systems
• Flow cytometry, cell and drug perfusion
• HTS and robotic systems
• Infusion and micro-dialysis
• LC applications – micro flow, micro gradients
• Mass spectroscopy sample introduction
• Micro diluters/dispensers for nl to ml range applications
• Micro liquid transfers for micro arrays
• Microtiter plate dispensing using multiposition valves
• Post-HPLC column reagent addition, stop flow, peak collection
• Precision dispensers and sampling devices (such as autosamplers)
• Sample introduction systems for ICP nebulizers
