Abstract

Disclosed is a pipette device which accommodates a detachable filling device and a detachable piston. The stroke length of the piston is determined by the selective engagement of an abutment, movable with the piston, with stepped surfaces cut into a sleeve movable within an enclosing housing. A control member accessible at the housing exterior is angularly shifted to move the sleeve and thus select the step with which the abutment will engage, thereby determining the length of the working stroke of the piston.
