Zusammenfassung:An improved method for measuring and dispensing fractions of a liquid sample in a device which comprises a casing having a vertical axis and containing a central chamber and transparent cells distributed around the chamber. Each cell is connected to the chamber by a closure cup. A capillary constriction separates each pocket from the corresponding cell. The improvement comprises adding polyvinylpyrollidone to the liquid sample.
