Plunger long 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 feature dual graduation and come with two plungers, a standard length to completely fill the bore and a second, shorter plunger for touch-off dispensing to prevent contamination. Wiretrol II is suitable for use with high and low viscosity liquids.
