1. Pressure vessel (1), comprising:
a reaction chamber (2) as a pressure space for the initiation and/or facilitation of chemical and/or physical pressure reactions of samples (P) accommodated in the reaction chamber (2),
a fluid inlet (20) with a feed valve (21) which is adjustable between an open position, for the feed of a fluid into the reaction chamber (2), and a closed position, for stopping the feed of the fluid,
a fluid outlet (30) with a discharge valve (31), which is adjustable between an open position, for the discharge of the fluid out of the reaction chamber (2), and a closed position, for stopping the discharge of the fluid out of the reaction chamber (2),
an oxygen sensor (33) for detecting an oxygen content in the reaction chamber (2),
a control device which is configured to control the feed valve (21) and the discharge valve (31) on the basis of the oxygen content detected by the oxygen sensor (33), such that the reaction chamber (2) is flushed via the feed and discharge valves (21, 31) situated in the open position, and at least the discharge valve (31) switches from the open position into the closed position as soon as a predetermined oxygen content is undershot,
further comprising a pressurized-air valve (40) for raising the reaction chamber (2) relative to the pressure vessel (1) by means of pressurized air fed into the pressure vessel (1) via the pressurized-air valve (40), wherein the control device is furthermore configured to automatically actuate the pressurized-air valve (40) in order to raise the reaction chamber (2) on the basis of an operating parameter detected by the control device.
