Abstract
A pipette for metering powder has a pipette sleeve and a metering piston having an end face for ejecting powder from the sleeve. The sleeve includes a free end and, on the sleeve inside, includes a circumferential wall extending in a closed manner around a longitudinal axis. The wall extends in the direction of the axis up to the free end and ends there in an edge which extends around the axis. The piston is guided to be movable parallel to the axis inside the wall. The end face, with the piston in a retracted metering position, defines a chamber with the wall. The wall is, in the region of the chamber, divided into a guide portion and a release portion adjoining the guide portion and extends up to the edge. The release portion surrounds a cross section of the chamber which is radially widened compared to the guide portion.
