The device includes at least one pressure sensor for detecting a pressure within the first receptacle. The device is designed such that a pressure difference between the first and the second ends of the first liquid line is greater than a predetermined minimum value when the first liquid line is connected with the process tank and the process tank is to be protected from contamination.
