Abstract

A filter cassette which is part of a filter system can be fastened to a sterile container lid. The sterile container lid serves to close a sterile container and to make a gas exchange possible between the container exterior and the container interior, without recontaminating the container material. In addition, the filter system fulfils a valve function. In order to center the filter cassette with respect to the sterile container lid, a first centering portion is provided on the filter cassette. The first centering portion interacts with a second centering portion on the sterile container wall section when the filter cassette is inserted into the sterile container lid.
