Abstract (en)
Piston pipette in which, on the outer face of the piston rod (7), there are grooves (10, 11, 12, 13) of different lengths, parallel to the piston rod and open at their upper end and, on the body, there is an inwardly projecting limiter pin (14) fitted as gliding in one of the grooves at a time, the said limiter pin, together with the closed bottom end of the groove, determining the upper extreme position of the piston. Moreover, onto the piston rod, a limiter sleeve (18) is fitted by means of a thread, and on the inside face of the body there is a stationary limiter flange (21), which, together with the limiter sleeve, determines the other extreme position of the piston.
