Abstract: A method and apparatus for inspecting pipette tips for defects. A holding device picks up multiple pipette tips from a first carrier. A first image acquisition device, with its optical axis aligned with the longitudinal axes of the tips, captures first image data of the pipette tip outlet openings. A second image acquisition device, with its optical axis transverse to the longitudinal axes, simultaneously captures second image data of the side surfaces of the multiple tips. A data processing system determines if the image data is within predefined limits. Pipette tips with data outside the limits are discarded, while tips with data within the limits are dispensed into a second carrier. The pipette tips may be rotated about their longitudinal axes during the acquisition of the second image data to check for concentricity.
