A system for measuring the amount of liquid aspirated into a micro-pipette tube comprising: a micro-pipette tube having a storage portion adapted to accommodate aspirated liquid therein and a tubular portion having a tip adapted for insertion into a liquid, the inner cross-section of said tube portion being greatly smaller than the inner cross-section of said storage portion, an end of said tubular portion opposite to said tip being in communication with said storage portion; means for applying suction to said storage portion for aspirating liquid thereinto through said tip and said tubular portion, and to maintain such aspirated liquid within the micro-pipette tube; a pressure measurement means coupled to the micro-pipette tube for measuring the potential hydraulic head of said aspirated liquid after deactivation of the suction applying means, and to provide a volume indication of the aspirated liquid.
