  • Patent number: 10207016
    Abstract: A sample preparation container, preferably for use in sterility testing, comprising a housing (1) having a housing wall (2) defining an inside space (3), a support on which a membrane filter is placed or is to be placed so as to get in contact with a sampling fluid to be introduced into the inside space (3), and at least one inlet opening (4) to the inside space (3) and at least one outlet opening from the inside space (3). A sampling port (5) is provided for allowing access from the outside to the inside space (3), wherein said sampling port (5) is closed by a septum (6) and the septum (6) is separated from the inside space (3) by a barrier wall (7) which is preferably piercable or breakable on application of an external force, preferably applied through a sampling instrument like a needle (8).

  • Patent number: 9956813
    Abstract: A dispenser for opening a tape like packaging comprising first and second films releasably connected to each other, forming envelopes sealed around an object, and disposed sequentially with a predetermined pitch. The dispenser comprises a space for holding a container of the packaging, a separator through which the packaging can be passed, for spreading apart and separating the films at an outlet thereof when a pulling force is acting on said first and second films, thereby opening envelopes and releasing the objects contained therein, and means for winding up separated first and second films of the tape like packaging. The separator further comprises a cover member that is articulated to the dispenser to be movable between a closed position and an open position.

  • Patent number: 9102909
    Abstract: The assembly comprises a filtration unit and a gel growth medium cassette, the unit and the cassette being adapted to cooperate in order to occupy a nested position in which a membrane covers the gel growth medium, the unit and the cassette each being equipped with an intermediate stop, it being possible for at least one of the two stops to move clear so as to allow the unit to move from an intermediate position, in which the membrane is spaced away from the said gel growth medium, into the nested position. The method comprises selecting such an assembly, of engaging the unit on the cassette until the intermediate stop of the unit comes into contact with the intermediate stop of the cassette, and the step of moving clear the stop able to move clear so as to allow the unit to move from the intermediate position into the nested position.
