Technology / Thought Leadership

Liquid properties such as viscosity, volatility, surface tension, or temperature can adversely affect the performance of your pipettes by having an impact on the volume of the air cushion inside the pipette. Additionally, air-displacement pipettes run a higher risk cross-contamination with biological samples and carryover of hazardous or radioactive liquids. For these situations, positive-displacement pipettes, such as MICROMAN® E, are a better tool for the job.

Positive-displacement technology, like that used in our MICROMAN® E pipettes, is ideal when working with infectious, viscous, foaming, hot, cold, or volatile liquids because the disposable piston within the capillary piston (CP) tip is in direct contact with the sample. The CP technology thus removes any air cushion inside the pipette and ensures the volume accuracy is not affected by the fluid's properties.
