A sampling valve (1), which is mounted on a container (5) has a valve stem (15) with a longitudinal bore (25), the front end of which opens into a cross bore (26) and is guided on this end in a sealed-tight manner inside an opening (7). The stem (15) is slidable between two positions by means of a lifting device (21). In the one end position the cross bore (26) opens into the interior space (6) of the container (5), in the other it opens into a valve chamber (10). The other end of the longitudinal bore (25) communicates with a nozzle (27), which is connected to an autosampler (72) via lines (67, 68) and a valve (70). The chamber (10) is connected to three valves (51-53) via a nozzle (33). The chamber (10) can be supplied with steam for sterilization purposes via the valve (51), and with sterile gas for transporting the extracted sample to the autosampler (72) via the valve (53). The device permits a practically loss-free, automatic, periodic extraction of small fluid samples from the container (5).
