A cap assembly for attachment to an equalization port on an endoscope, comprising:

• a tubular housing having a first end and a second end and defining an internal chamber extending from said first end to said second end;
• a mounting section releasably attached to said second end of said housing in fluid-tight fashion, said mounting section dimensioned to be attached to said equalization port of an endoscope in fluid-tight fashion, wherein said internal chamber communicates with said equalization port;
• a barrier layer formed of a reactive material that is capable of absorbing or breaking down a gaseous germicide, said barrier layer disposed within said internal chamber between said first end and said second end of said housing;
• a first cavity defined between said barrier layer and said first end of said housing;
• a second cavity defined between said barrier layer and said mounting section, said second cavity dimensioned to receive an indicator test strip that is capable of detecting said gaseous germicide;
• and
• a filter layer disposed between said barrier layer and said first end of said housing operable to filter flow through said housing.
