Abstract
A method and a device are provided for contamination-free and/or sterile sealing between two interconnectable connecting elements having opposing openings. Interconnection allows transfer of a fluid between the openings. Sealing elements are arranged on the connecting elements around the openings, and protective films are provided, covering the sealing elements and the openings and adapted to be removed in the final interconnection. The sealing elements are each provided with at least one recess which extends wholly or partly around the associated opening and receives a gas. In use the sealing elements are moved into engagement with each other, interleaved with the protective films, to reduce the volume of the recesses and, thus, increase the pressure of the gas therein. During removal of the protective films, the gas flows out of the recesses to the environment to prevent penetration of contamination into the openings.
