ABSTRACT:
A precision micropipettor device, primarily useful for dispensing a predetermined, accurate fixed volume quantity of fluid, includes a tubular fluid holding barrel having a dispensing end and a working end, a removable fluid holding outlet conduit secured to the dispensing end, a plunger shaft assembly for reciprocal movement within the tubular fluid holding barrel to dispense reagent contained in the fluid holding outlet conduit, and a mechanism for predetermining the range of movements of the plunger shaft assembly along the longitudinal length of the fluid holding barrel. The device can repeatedly dispense an accurate predetermined quantity of fluid. The device includes visual indication elements for communicating to an operator the resting position of the plunger shaft assembly. The device also includes a spring for returning the plunger shaft assembly to a preferred resting position after each use which spring by itself may constitute the mechanism for predetermining the range of plunger movement.
