Abstract (en)
[origin: US4362064A] High-precision positive-displacement pipette having a nozzle with calibrated capillary channel and capable of disengageably fitting together with the free lower end of the pipette body. A piston fits tightly in the capillary channel and is controlled by a manually operable control rod equipped with a gripping device with which it grips the piston. An opening at this end of the body permits at least a part of the gripping device to pass through and come into contact with a stop provided on the inner surface of the nozzle so as to ensure the simultaneous ejection of the nozzle and of the piston which remains captive in the capillary channel.
