Abstract
The invention provides a valve () for sterile transfer of fluids. The valve () comprises a housing () having first and second open ends () and a passageway () extending between the ends (). The first end () has a flange () for coupling the housing () about an opening () of an external conduit () and a seal blocking an open area of the first end (). The seal is placed in register with the opening () of the external conduit (). The valve () has a piston () movably disposed within the housing () so as to interrupt the seal and to permit fluid to pass along the passageway (). A mating surface () of the flange () and the seal form a sterilizable surface. The seal is formed between a plastic plug () movable by the piston () and a sharp plastics rim () which encompasses the open area of a first end () of the housing ().
