Technical Examples

An air-filled pipette for accurately metering small and large volumes of fluid samples is provided. The pipette has dual resolution capability such that the pipette can accurately aspirate a wide range of sample volumes and deliver them contact-free (touchless). The pipette may include an extension mandrel that reduces air space in a disposable tip within the pipette. The dual resolution capability and/or the extension mandrel also minimize errors associated with the compressibility of air. Multiple pipettes may also be arranged to form a pipetting module for the metering of multiple sample volumes simultaneously and automatically. The pipette includes a channel block having at least one cylindrical passage, that slides up and down over a rod, and a cylinder, with an axially extending passage therethrough, that is sized, shaped and aligned to fit into the cylindrical passage in a dynamic sealing relationship. A method for mixing multiple fluid samples within a pipette tip is also provided.
