Abstract
Abstract The invention deals with a container for receiving a culture medium of microorganisms. The container 20, which may be sealed by a film 28, comprises two substantially cylindrical and concentric elements 21 and 22, the inner one of which comprises a bottom portion 24 defining a hollow portion 25 for receiving the culture medium, both of said concentric elements being connected through a circular crown 23 provided with one or more axial holes 26. This container is particularly useful with the microbiological testing device and method of the parent EP-A-0150,775.
