1. A cartridge system comprising:
a cartridge for receiving a medium to be dosed,
a stator being provided on the cartridge, which cooperates with a rotor unit of an eccentric screw pump for dosing the medium, and
a plug being movably supported in the cartridge for a fluid-tight closure of the cartridge, wherein the plug comprises a rotor breakthrough through which the rotor unit can be passed, wherein
the rotor breakthrough is closed by means of a membrane facing the stator.
