Pipets, Pipet Accessories, Fast-Release Pipette Pump

This fast-release pipetting device provides easy, precise pipetting and features a rapid release lever for zip quick emptying. It is made expressly for pipettes that are calibrated to the tip but not to be blown out (retains final drop). Rotating the knurled thumbwheel draws up or dispenses liquid. The soft elastic chuck has a threaded collar that tightens to grip glass or plastic pipettes securely. Easy to take apart for cleaning. Sizes are color-coded.
