Pressure vessel system

A pressure vessel system (1) comprising:

• a pressure vessel (2) having a reaction chamber (3) as a pressure space for initiating and/or promoting chemical and/or physical pressure reactions of samples (P) accommodated in the reaction chamber (3), and
• a rigid rail (50) which is rigidly connected to a part of the pressure vessel (2) and has a first connection (51) to a fluid inlet, a second connection (52) to a fluid outlet and a fluid conduit (53) which fluidically connects the first connection (51) to the second connection (52),
• wherein the fluid conduit (53) is fluidically connected to the reaction chamber (3) via the second connection (52),
• wherein the rail (50) has at least one third connection (55) which is fluidically connected to the fluid conduit (53) and can be connected to a device (56), so that the device (56) is fluidically connected to the fluid conduit (53) and thus to the reaction chamber (3),
• wherein the fluid conduit is provided integrally with the rigid rail,
• wherein the pressure vessel (2) has a lid (5) which can be moved between an open position, in which the reaction chamber (3) is open, and a closed position, in which the reaction chamber (3) is closed, and wherein the rail (50) is rigidly connected to the lid (5),
• wherein the rail (50) is configured and connected to the lid (5) in such a way that the lid (5) can be moved between the open position and the closed position by moving the rail (50), and
• wherein the rail (50) is configured and connected to the lid (5) in such a way that the lid (5) can be moved between the open position and the closed position by vertically moving the rail (50).
