Ergonomic Positive Displacement Pipette

Problem-free pipetting of problem Liquids: The Pos-D is specially suited for liquids with high densities, viscosities or vapor pressures. Given the disposable capillaries and pistons, positive displacement absolutely eliminates cross-contamination from aerosols, samples or pipette.
A disposable piston, which moves within a plastic capillary, makes direct contact with the liquid.
The positive wiping action of the piston against the capillary wall assures complete dispensing without droplets.

The pre-assembled capillary tips are easy to use and
also fit Gilson Microman®.
