Abstract

The application discloses a device for drawing a liquid from a process tank to be protected from contamination, including: a first receptacle for receiving the liquid withdrawn from the process tank; a first liquid line connecting the process tank with the first receptacle; and at least one first valve assembly disposed in the first liquid line and designed to block or release liquid transport through the first liquid line. 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.
