METHOD FOR IMPROVED MICROBIOLOGICAL TESTING

摘要

An improved method for microbiological testing of a liquid sample in a device which comprises a casing having a vertical axis and containing a central chamber and transparent cells containing growth media 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 transparent cells to stimulate a homogeneous bacterial growth.
