A sampling system has a first connecting piece for connecting to a pipe traversed by fluid and a third connecting piece, and a cock which has a basic body with a longitudinal axis, about which the cock can be pivoted between a first end position and a second end position. The sampling system further has a sampling recess. In the first end position, the sampling recess can be connected via the first connecting piece to the pipe traversed by media. In the second end position, the sampling recess can be connected to the third connecting piece, in which the third connecting piece is connected to a first end of an extraction needle which can be pierced with a second end through a membrane of a sampling volume. In the second end position, the sampling recess is connected via the third connecting piece to a first end of a ventilation needle.
