ABSTRACT:
An arrangement and device for on-line liquid sampling in which small samples of a liquid, particularly a sterilizable liquid, flowing through a pipe are periodically withdrawn. Sterilization of the sampling device together with a collecting container attached thereto is made possible without exposure of the device to the atmosphere as the device is mounted on the pipe. This is achieved by enveloping the sampling device with the collection container attached thereto by a flexible, high-temperature resistant enclosure such as a plastic bag, which normally seals off the liquid entry port to the device; sterilizing the device and container assembly in this condition; and providing the pressure air actuated valve in the device which serves to close the normally open valve seat to trap a sample of the liquid, with an extension which punctures the bag adjacent to the entry port incident to the actuation of the valve. The design of the device has also been improved in various respects to simplify its construction and improve its accuracy, convenience and sanitary performance in operation.
