Positive-Displacement Pipette MR-250
Positive Displacement Pipetting. Pos-D™ positive-displacement pipette, 50-250 μL, for dense, viscous or volatile liquids. Uses Rainin capillary-pistons #17008608 (MR-250)
Problem Liquids? No Problem
Pos-D is designed and especially suited for non-aqueous liquids: dense, viscous, high vapor pressures, etc.
With its natural feel and ergonomic finger-hook, the Pos-D fits comfortably in your hand. And the display is always visible.
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.
The pre-assembled capillary tips are easy to use and
also fit Gilson Microman®.
