AutoPipettor - Precision Aspirating And Dispensing Module




Fluid Circulation Metering System

IVEK’s AutoPipettor has been carefully developed to provide life science instrument developers and manufacturers with an electronically controlled pipettor for precise and reliable liquid handling. With the functionality of an electronic pipettor, small and large sample allquots are effortlessly managed.

Functioning as an air displacement mechanism, liquid dispensing capabilities and performance are enhanced due to a closefitting ceramic-on-ceramic piston and cylinder set. The piston is coupled to a stepper motor driven linear actuator that creates tightly controlled piston motion, yielding outstanding accuracy, precision and reliability.
