Title: Apparatus for volume measurement of liquids

Abstract: A liquid volume measuring apparatus in constructed to simultaneously solve the problems of accuracy of measurement, contamination of the liquid, and speed of operation. This apparatus utilizes a containing element for the liquid to be transferred, an aspiration system for filling the containing element, and a control liquid being immiscible with the liquid to be transferred to form a liquid piston to distribute the liquid without an air dead space therebetween, and to simultaneously act as a cleaning agent of the containing element. By this means, another different liquid can be dispensed by the apparatus without contamination by the previously dispensed liquid.
