<p>The invention relates to a sampler (1) for liquid substances, especially a water sampler, comprising a body (2), a sampling container (3) fitted with a sealable bottom (6) and cover (7), as well as means for closing said sampling container (3) of sampler (1) to be immersed in liquid upon a lowering cable (8), said closing being effected at a desired depth by means of a weight (13) to be dropped along said cable. Said sampling container (3) is mounted for axial movement on body (2) external of the container. Body (2) is provided with a release mechanism (4) from which container (3) can be suspended in an upper position relative to body (2) upon a laterally hinged cover (7) which is in an open position. Means (10, 11) are provided for locking the laterally hinged bottom (6) of said upper positioned container (3) in an open position. The container (3) released by release mechanism (4) is adapted to slide under gravity along body (2) down to a lower position, said cover (7) being adapted to close by the action of gravity and bottom (6) and/or the lower section of body (2) is provided with means which, as container (3) is moving downwards under gravity, for bottom (6) to close and to remain closed.</p> |
