The system for removing a liquid sample from a tube (12), which has a widened transverse welded seam (14). It has a cylindrical body (1) with a blind hole (2). A hollow needle (5) passes through a connecting piece (4) formed at the body (1). At the free end of the connecting piece, a container wall (23) is designed, spaced and coaxially surrounding the corresp. section of the hollow needle (5), which forms a cavity (24) open to the tip (21) of the hollow needle. The container wall (23) surrounding the cavity (24) has an external diameter, which is smaller than that of the connecting piece (4). The height of the part of the hollow needle extending over the cavity (24) is slightly smaller than the height of the container wall (23). |
