Method for moving a processing vial between locations of an instrument

A method for moving a processing vial between locations of an instrument. The method includes the steps of dispensing a fluid into a processing vial with a disposable pipette tip frictionally fitted onto a probe of a pipettor, stripping the disposable pipette tip from the probe of the pipettor, and then engaging a cap in a frictional fit with the probe of the pipettor. While the cap is engaged in a frictional fit with the probe of the pipettor, coupling the cap to the processing vial to form a cap/vial assembly, where the cap seals the processing vial. The pipettor moves the cap/vial assembly from a first location of an instrument to a second location of the instrument. At the second location of the instrument, the cap/vial assembly is ejected from the probe of the pipettor, thereby depositing the cap/vial assembly at the second location.
