A test plug for in-situ testing a glove installed in a glovebox is provided that uses a top plate and a base plate, and a diametrically expandable sealing mechanism fitting between the two plates. The sealing mechanism engages the base plate to diametrically expand when the variable distance between the top plate and the bottom plate is reduced. An inlet valve included on the top plate is used to introducing a pressurized gas to the interior of the glove, and a pressure gauge located on the top plate is used to monitor the interior glove pressure.

In-situ leak testing of glovebox, isolator, or containment unit gloves

Condensation polymerization followed by a supercritical extraction step can be used to obtain highly cross-linked nanoporous polymers with high surface area, controlled pore sizes and rigid structural integrity. The invention polymers are useful for applications requiring separation membranes.
