Abstract: An apparatus for processing a laboratory sample contained in a laboratory sample container is presented. The apparatus comprises an optical sensing unit for sensing a transmittance at different vertical positions through the laboratory sample container and a tip sensing unit having a tip. The tip sensing unit is adapted to provide a tip sensing signal (tLDS) depending on a position of the tip relative to the sample. The apparatus also comprises a process control unit adapted to control the secure and reliable pipetting of the laboratory sample in response to both the transmittance and the tip sensing signal (tLDS) provided by the tip sensing unit.
