Abstract: The invention relates to a pressure vessel, having: 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, preferably a flushing gas, 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 a fluid out of the reaction chamber (2), and a closed position, for stopping the discharge of the fluid out of the reaction chamber (2); and an oxygen sensor (33) for detecting an oxygen content in the reaction chamber (2).

Abstract: The present invention relates to a pressure vessel (1) having a pressure vessel wall (1a) which completely surrounds a reaction chamber (2) as a pressure space for the initiation and/or promotion of chemical and/or physical pressure reactions of a sample (P) to be heated which is accommodated in the reaction chamber (2), wherein the pressure vessel wall (1a) has an infrared-permeable high-pressure window (30) which extends away outward in a direction from the reaction chamber (2) and which is supported in the pressure vessel wall (1a) with respect to a pressure in the reaction chamber (2), wherein the pressure vessel (1) furthermore has an infrared to temperature sensor (40) which is situated directly opposite the high-pressure window (30), in order to measure the temperature of a sample (P), accommodated in the reaction chamber (2), during a pressure reaction through the high-pressure window (30).

Abstract: The present invention relates to a pressure vessel (1) for receiving samples (P) to be heated, having a reaction chamber (2) as a pressure space for the initiation and/or facilitation of chemical and/or physical pressure reactions, the reaction chamber (2) being designed for receiving a liquid (5), a magnetic disk (8) mounted rotatably about an axis of rotation in the reaction chamber (2), and a magnet arrangement (10), provided outside the reaction chamber (2), for generating a rotating magnetic field for rotationally driving the magnetic disk (8) about its axis of rotation, the magnetic disk (8) having at least one passage bore (13), which extends transversely in relation to the axis of rotation and is provided in such a way that liquid (5) received in the reaction chamber (2) is driven through the passage opening (13) by rotation of the magnetic disk (8) in order to stir the liquid (5).
