  • Patent number: 9079178
    Abstract: Pipette tips of different sizes may be coupled to a pipettor without needing to modify the pipettor. The same pipettor may thus be utilized to exchange different pipette tips, which may be done in an automated manner. Pipette tips may be coupled to adaptors that include proximal ends for interfacing with the pipettor and distal ends for interfacing with pipette tips. The proximal ends may all have the same geometry, matched with the same pipettor. The distal ends may have different geometries matched with different pipette tips. A pipettor may be part of a liquid handling apparatus and movable in an automated manner to different deck positions. The pipettor may include a locking mechanism for locking adaptors to the pipettor or locking pipette tips directly to the pipettors, and an ejection mechanism for ejecting pipette tips from corresponding adaptors.
