Abstract
The invention relates to a pipetting device having an exchangeable pipette tip for suctioning and discharging fluid volumes for use in automated laboratory systems. The invention relates to a pipetting device having a pipette tip detection unit and for detecting a pipette tip on a pipette device of this type. A detection unit detects whether a pipette tip is connected to the pipette tube or determines a characteristic feature of the connected pipette tip. The pipette tip forms at least one portion of a first electrode when the pipette tip is in electrical operative contact with the pipette tube and, e.g., a pipette tip holder, a contact for setting down the pipette tip holder or a working table over which the pipette tube can be moved forms at least one portion of a second electrode.
