Abstract

Mechanisms are provided for automatically removing tips from a pipette nozzle and/or for detecting the type of tip mounted to the nozzle. For detipping, mechanical energy is stored when the tip is mounted to the nozzle and is released when the tip is to be removed to facilitate removal thereof. A mechanism is preferably provided which limits the force with which the tip is mounted to the nozzle and an overforce mechanism may be provided to facilitate removal of a stuck tip. For detecting tip type, each tip type has a different base configuration which results in a different relative displacement between the nozzle and a surrounding component as a result of the tip contacting both during tip mounting, the difference in relative displacement being detected to identify tip type.
