Plunger for Wiretrol II 25-50µl (1 pc.)

Wiretrol II positive displacement micropipettes combine a precision bore, calibrated disposable micropipette with a reusable stainless steel plunger and fingertip holder.
The calibrated micropipettes have dual graduation and are supplied with two plungers, one of standard length for filling the bore completely and a second shorter plunger for touch-off delivery of the sample to avoid contamination. Wiretrol II is suitable for use with both high and low viscosity liquids.
