With increasing step length, a path limitation device (29, 29') controlled by the step length adjustment device (23, 27) increases the operating path (B) of the operating element (17), and decreases it with decreasing step length.

There is a step length adjustment device (23, 27) to adjust the step length of each step forward, which has a movable restraining element (23) to keep the latch from engaging with the gear rack. When the operating element moves back again, the latch disengages from the gear rack. This latch engages and moves a step forwards with the teeth (14) of the gear rack when the operating element moves forwards. There is a device (10) to push the receptor body away from the injector uptake, and a device (13, 17, 22) to push the body towards the uptake, which has a gear rack (13) attached to the body, an operating element movable along an operating path (B), and a swivelling latch (22) mounted against it. Repeating pipette has an injection inlet (5) for the fastening section of an injector (6), a receptor body (9) with a piston uptake for the operation section of an injection piston. for dispensing multiple doses from a single charge with only one conduit for withdrawing and redistributing liquids of the plunger pump type with only one conduit for withdrawing and redistributing liquids
