Abstract
A dispenser for taking up and discharging fluid volumes which has an exchangeable piston-cylinder unit. The dispenser has a housing and a device for incremental distance measurement that, when there is relative movement between the piston and the cylinder, the distance traveled by the piston relative to the housing can be determined incrementally. The dispenser has a piston actuation member which can be releasably connected to the piston moving the piston in order to take up and/or discharge fluid volumes. The dispenser has a position determining device which has a first position element and a second position element. The first position element is fixed in or on the housing of the dispenser. The second position element is coupled so as to be able to move with the piston actuation member. The position determining device is for continuously sensing the position of the second position element.
