Mechanical pipette Pos-D™

positive displacementcapillarypiston

A positive displacement pipette eliminates cross-contamination from aerosols, samples or other pipettes. The Pos-D positive displacement pipette is a smart solution for pipetting "difficult" liquids, such as dense, viscous and volatile samples. Pos-D is specially suited for liquids with high densities, viscosities or vapor pressures. A disposable piston, which moves within a plastic capillary, makes direct contact with the liquid. Pos-D is designed and especially suited for non-aqueous liquids: dense, viscous, high vapor pressures, etc. Hand-Friendly With its natural feel and ergonomic finger-hook, the Pos-D fits comfortably in your hand. And the display is always visible. No Cross-Contamination Disposable capillaries/pistons, with direct contact between sample and piston, means no aerosols and no cross-contamination. 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.
