Abstract
The present invention relates to a detachable barrel assembly for use with an electronically monitored mechanical pipette. The detachable barrel is made to retain all internal elements thereof in proper operating position even when the barrel assembly is detached from the pipette. The barrel assembly may be of a single channel or multi channel configuration. The barrel assembly may be removed from the pipette in order to allow it to be cleaned, such as by autoclaving, and reattached to the pipette. In this manner, the electrical components of the pipette itself do not need to be subjected to autoclaving whenever the barrel assembly needs to be cleaned. Further, the self-contained design of the barrel assembly simplifies detachment and reattachment thereof to the pipette.
