ABSTRACT:
A sealed system is provided for facilitating the transfer of material through a port in a barrier wall separating two different environments without contamination of the cleaner of the two environments by the dirtier. The system includes a door closing a port in the barrier wall in leak-proof sealed engagement. A transfer medium for containing or receiving the material to be transferred through the port is provided with a removable cover in leak-proof sealed engagement within a transfer medium ring connectable in leak-proof sealed engagement with a stationary ring defining the passage through the barrier wall which is closed by the door. Sealing rings are provided between the door and transfer medium cover, and between the transfer medium ring and stationary ring to ensure against passage of contaminants from one environment to the other. For certain pharmaceutical applications, a heating element is provided in the stationary ring to sterilize the interfaces between abutting parts.
