Abstract: A container for a culture medium having a dish and a lid, and having an integrated geometry for air suction and air conduction. The container being adapted for analysis of air bacteria according to the impaction method. An adapted cascade connecting hood, which can be disposed between two successive containers, makes possible a cascade-like serial arrangement of a plurality of culture medium containers, which, with suction apertures of differing size, allows a differentiation according to particle size when analyzing air bacteria.
