Wiretrol II Micropipettes 50-100µl (250 pcs.)

Wiretrol II positive displacement micropipettes combine a calibrated, precision-bore disposable micropipette with a reusable stainless-steel plunger and a fingertip handle. The calibrated micropipettes feature dual graduations and come with two plungers: one standard length for complete filling of the bore, and a second, shorter plunger for non-contact sample delivery to prevent contamination. Wiretrol II is suitable for use with high and low viscosity liquids.
