Abstract

The invention relates to a step pipette, which has a metering rod and, attached to this, a metering toothing 7, a beating member 8 corresponding to the metering toothing, a fill rod joined by means of gearwheels to the metering rod, a striker spring 12 and a release member 18 for releasing the tension of the striker spring after the last full-length stroke. As a result of this solution, even the last dose of liquid is guaranteed to be full. <IMAGE>
