Abstract

A filter module (10) has a housing (12) which is subdivided by a membrane filter (14) into an inlet chamber (16), which is connected to an inlet connecting piece (22) arranged rigidly on the housing (12), and an outlet chamber (18), which has a filtrate outlet (20). The inlet connecting piece has two connectors, specifically a first connector (26) and a second connector (28), which connect selectively and fluidically to the inlet chamber with a 3-way valve (24) integrated into the inlet connecting piece. The valve has a first entry, which is connected to the first connector, a second entry, which is connected to the second connector, and an exit, which is connected to the inlet chamber. The first connector is configured as an adapter for outwardly sealed coupling of a culture medium bottle (30), which coupling permits a gravity-driven exchange of liquid with the first entry of the valve.
