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.

A fluid transfer system for transferring a substance from a first vessel to a second vessel avoiding contamination, said system being attached or connectible to said first vessel or a cover enclosing the first vessel, comprising: (1) a first member hermetically enclosing a puncturing member provided with a passageway, said first member having a first sealing member for being passed and retracted therethrough, at which the sealing effect of said sealing member is maintained after retraction of the puncturing member; (2) a second member having a second sealing member; mating connection means arranged on said first and second members for providing a releasable locking of said members with respect to each other, said sealing members in the connected position of the first and second members being located in a position with respect to each other so that they can be penetrated by the puncturing member, wherein after transfer of said substance the puncturing member is retractable to a position in which said puncturing member is hermetically enclosed in said first member and the first and second members are disconnectable from each other.
