Patent ID: 7819934

Claim:
An apparatus comprising: a vessel or a processing device having an interior comprising a container adapted for containing a liquid; an environmental containment enclosure having an inner surface and configured for surrounding at least a portion of the vessel or the processing device, the environmental containment enclosure being configured so that at least a portion of the environmental containment enclosure has a shape and/or contour that is complementary to a shape and/or contour of an outer surface of the vessel or an outer surface of the processing device to which the at least a portion of the environmental containment enclosure is adjacent; the inner surface of the environmental containment enclosure and the outer surface of the vessel or the processing device defining an enclosed space therebetween, at least a portion of said enclosed space not in continuous fluid communication with an interior portion of the container, and wherein said enclosed space is maintained during use of the vessel or the processing device at a pressure chosen from greater than atmospheric pressure, less than atmospheric pressure, and equal to atmospheric pressure; an environmental treatment system in communication with the enclosed space, the environmental treatment system comprising a ventilation system in fluid communication with the enclosed space, the ventilation system comprising an inlet port dimensioned for connection to a source of gas unit for introducing gas into the apparatus and an outlet port for connection to an exhaust unit for removing a gas from the apparatus; and a damper control configured for connection to at least one of the source of gas unit and the exhaust unit, the damper control capable of regulating pressurization within the apparatus; and wherein the environmental treatment system and environmental containment enclosure are configured to maintain an aseptic and/or substantially particle-free environment within the enclosed space.
