Abstract
The present invention concerns a pipette comprising a mechanism with which the stroke length of a piston can be changed by rotating the piston rod. The pipette comprises a locking mechanism which prevents the rotation of the piston rod when the piston has been pushed a certain distance downwards from its upper position, but does not prevent the rotation when the piston is in its upper position.
