PROBLEM TO BE SOLVED: To provide a coupling device for fluid transfer that prevents contamination of fluid.SOLUTION: The coupling device for fluid transfer is described, which includes first and second connectable coupling members that together contain a sealed interior space when connected. A gas or steam purge inlet and a purge outlet are disposed in fluid communication with the sealed interior space for purging potential contaminants out of the interior space. The coupling device also includes a vacuum port in fluid communication with the sealed interior space for vacuuming the sealed interior space and optionally testing the space for an adequate seal. The first coupling member includes a first fluid transfer conduit, and the second coupling member includes a second fluid transfer conduit. The first and second fluid transfer conduits are positioned such that they can be connected together within the sealed interior space when the first and second coupling members are connected. |
