When the stopper (3) is in the upper position, it allows air blown in via the cannula (6) to scavenge the interior space of the tube (1) until the control (11,12, or 13) has indicated a sufficient volume. The cannula (6) is then pulled by the operator so that a blind stop (7) obturates the opening of an evacuation pipe (10) connected to the control.
