ABSTRACT:
A device is disclosed for preventing air contamination when transferring a substance from one vessel to a second vessel. The device is attached or connectible to the vessel and comprises a first member, in which a puncturing member e.g. a needle, provided with a passage is enclosed. The first member has a sealing member, e.g. a membrane, through which the needle can be passed. The device further comprises a second chamber, which is detachably connectable to the first member and which also has a sealing member, e.g. a membrane. When the first and second members are connected to each other the two sealing members are located in a position with respect to each other so that they can be penetrated by the puncturing member which is movable with respect to the sealing members.
