Abstract
This concerns a device whose filtering membrane is gripped annularly at the periphery between a first member forming part of an intake body and a second member forming part of a drainage body with one out of the first member and second member having an elastomer seal by means of which it comes into contact with the membrane, and whose locking means are adapted to allow the opening of the device by requiring only a separation movement between said first member and said second member. The drainage method proposes directly placing the device on a vacuum flask, the sealing with regard to the stopper of said flask being obtained by a rib tapering towards its end.
