Rainin Pipet-Lite PL is one of the most ergonomic universal-fit manual pipettes available. Accurate and precise, Pipet-Lite PL delivers light and smooth operation even after hours of pipetting. It is a favorite of research scientists for its ruggedness and dependability, and offers the lowest plunger forces of any manual pipette – about 35% less than most similar pipettes. A shock absorber built into the tip ejector helps protect the thumb.
