Abstract:
1. A suction device for closures of sample containers, including a suction passage ( 1 ), a vacuum space, which constitutes a reservoir ( 2 ), and a blower ( 5 ) which produces, in use, a vacuum in the reservoir ( 2 ), the reservoir ( 2 ) having on its underside a closure flap ( 4 ) that is mounted with a substantially horizontal pivotal shaft ( 11 ) and has a counterweight ( 13 ) which is sized so that the closure flap ( 4 ) is substantially closed when the reservoir ( 2 ) is empty, and the blower is off, so that the closure flap ( 4 ) is in a fully closed position when a vacuum is produced in the reservoir, and pivots, when the vacuum drops off, into an open position under a weight of one or more closures.
