A transfer port system to allow material to transfer between two dockable sterile environments. Two doors provide access to the sterile environments. A peripheral flange frames one of the doors while another peripheral flange forms the opening to the other sterile environment. Doors connect to one another, when the sterile environments are docked, and then move as a unit into the one sterile environment in order to allow the material transfer. Outer and inner gaskets seal the sterile environments and with the peripheral flanges form an interface between the sterile environments during material transfer. The portions of the gaskets and peripheral flanges that were exposed to the unsterile ambient prior to docking are actively heated in order to maintain sterility during the time when the sterile environments are docked and prior to the time that the doors are moved to the open position. The doors can be connected to one another prior to their opening by vacuum. The vacuum has an added benefit of drawing contaminants from between the doors.

Interface de transfert permettant de transférer des matières entre deux environnements stériles se prêtant à l'amarrage. Deux portes permettent l'accès aux environnements stériles. Une bride périphérique enserre l'une des portes, tandis qu'une autre bride périphérique sert d'ouverture à l'autre environnement stérile. Les deux portes peuvent être raccordées l'une à l'autre lorsque les environnements stériles sont amarrés, et peuvent être déplacées comme entité dans un des environnements stériles pour permettre le transfert des matières. Des joints d'étanchéité internes et externes assurent l'étanchéité des environnements stériles et forment, avec la bride périphérique, une interface entre les environnements stériles durant le transfert des matières. Les portions des joints d'étanchéité et des brides périphériques exposées à l'air ambiant non stérile avant l'amarrage sont chauffées activement pour assurer la stérilité durant l'amarrage et avant que les portes ne soient ouvertes. Les portes peuvent être raccordées l'une à l'une avant leur ouverture par dépression. La dépression contribue à l'extraction des contaminants qui se trouveraient entre les portes.
