The bottle has a cylindrical body (1) that is provided with a set of ends, where the body is closed at each of its ends by a set of stoppers (2, 3) to form an enclosure (5) for receiving hydrocarbon samples. The enclosure is arranged with a valve (6). The valve is arranged with a reversed needle presenting a truncated head or conical wall converging in the direction of a seat located downstream from a purging circuit. A washer is associated with a pre-sealing jacket, where the washer is arranged with a frontal surface. |
