Abstract A sample container (1) especially for oil/gas samples con- sists mainly of a spherical body formed of two half parts (2,3) with ametal membrane (4) fixed between the flanges of the two half parts. The membrane has a configuration com- plementary to the configuration of each half part and is substantially hemispherical with a planar portion (8) perpen- dicular to the in-/outlet passages (9,10). The flange (13) of the membrane forms the packing between the two halves of the container. The membrane may be equipped with a reinforcement plate (14) perpendicular to the in-/outlet passages. To ensure that the container is leakage proof at large pressure variations, the container is at the oil/gas side equipped with a resilient packing nose (16) and labyrinth packing (17). The in-/outlet passages are formed as annular gaps (21). The container has only metallic packings.
