Wiretrol II Micropipettes 25-50µl (250 pcs)

Wiretrol II positive displacement micropipettes combine a precision bore, calibrated disposable micropipette with a reusable stainless steel plunger and a finger-grip holder. The calibrated micropipettes are double-graduated and come with two plungers, a standard length for filling the bore completely and a second, shorter plunger for touch-off dispensing of the sample to avoid contamination. Wiretrol II is suitable for use with both high and low viscosity liquids.
