The pipette (1) has a decoupling device (44) for decoupling a drive element (34) i.e. sleeve, from a cylindrical lifting rod (6) during contact of a circular collar (38) at an overlifting spring bearing (32) and continued displacement of an actuating element (4) in an actuating direction. A lower stop body (27) is coupled with the rod, and strikes an actuating end of a dropping extension (74) during decoupling of the drive element from the rod for downwardly displacing the extension and a dropping slider (72) during displacement of the drive element in the actuating direction. |
