Abstract
A dual-filter dual-integrity test conduit assembly allows for in-situ testing of both filters with separate, duplicate systems for membrane integrity so that if the first tester filter fails, the second filter may be tested with a different, but identical method with its own gauges and nitrogen supply so as to further isolate malfunctions of the filter integrity test equipment as a cause for erroneous batch failures.
