ABSTRACT:
An apparatus for extracting samples of product such as liquid or gas from a product chamber. The apparatus comprises a sample chamber arranged in a housing for movement between positions projected into and retracted from the product chamber. The housing is connected to a lateral side of the product chamber in such a manner as to surround an opening thereof in a sealing relation. The apparatus further has a product outlet and a plunger that includes the sample chamber and is supported for axial movement in the housing which is configured as a cylinder.
