Abstract
A closed receptacle has a wall defining an internal space in which the sampling cell is fixed in a stable position, and an external wall into which opens, through an aperture, a connecting conduit connected to the internal space. The receptacle has a removable seal which seals the periphery of the aperture. The apparatus includes a removable means for testing the receptacle, which defines together with the external wall of the receptacle, a sealed zone surrounding the connecting conduit and which communicates with pressure measuring means. The removable testing means includes a key for loosening and tightening the removable seal to permit testing the receptacle for sample leakage without loss of the contents of the receptacle.
