Method and device for checking pipette tips

An apparatus for inspecting pipette tips each extending along a longitudinal axis (L), the apparatus comprising:

• a receiving position configured to provide a first carrier containing pipette tips;
• a holding device for picking up pipette tips from the first carrier provided at the receiving position, the holding device comprising a plurality of pick-up elements, which pick-up elements are configured for receiving one pipette tip each;
• a first image acquisition device for acquiring first image data of the respective pipette tip outlet openings of the pipette tips picked up by the holding device;
• a second image acquisition device for acquiring second image data of the pipette tips held in the holding device;
• a data processing system which is signal-conductively connected to the first image acquisition device, the second image acquisition device and the holding device, and in which allowable limits for at least one of the first and the second image data are predefined;
• a waste container configured to receive pipette tips discarded by the holding device;
• a dispensing position on which a second carrier can be provided;
• the apparatus comprising means for aligning the optical axis (OA1) of the first image acquisition device parallel to the respective longitudinal axis (L) of the pipette tips held in the holding device and onto the respective pipette tip outlet openings, and for aligning the optical axis (OA2) of the second image acquisition device transverse to the respective longitudinal axis (L) of the pipette tips held in the holding device and onto the partial segments of the respective pipette tip jacket surfaces of the held pipette tips facing the second image acquisition device, said holding device being movable back and forth between at least two of said receiving position, said first image acquisition device, said second image acquisition device, said waste container and said dispensing position.
