Pipette tip separating system

Separating apparatus for pipette tips, each having a longitudinal axis, comprising:

• a feed device for feeding pipette tips,
• a dispensing device for dispensing pipette tips,
• a separating device arranged between the feed device and the dispensing device and having a transport shaft mounted rotatable about a longitudinal axis and a holding element, arranged spaced apart from the transport shaft, for holding the pipette tips, wherein the pipette tips can be held in a friction- and positive-locking manner between the holding element and the transport shaft, and wherein the transport shaft is provided, at least in areas, with a thread, by means of which the pipette tips can be moved in an intermediate space between the transport shaft and the holding element along the longitudinal axis of the transport shaft, wherein the thread of the transport shaft is formed as a groove so that the pipette tips can be held in a positive-locking manner in the longitudinal direction of the transport shaft, and wherein the longitudinal axes of the pipette tips are arranged substantially perpendicular to the longitudinal axis of the transport shaft during the movement, and wherein the transport shaft has a transfer area for transferring the pipette tips from the feed device, wherein the thread has a first thread pitch in the transfer area, wherein the transport shaft has an acceleration area arranged after the transfer area, wherein the thread has a second thread pitch, which is greater than the first thread pitch, in the acceleration area.
