An apparatus for testing the efficacy of a sterilizing environment on a test indicator, comprising a test chamber, a loading chamber adjacent to the test chamber and an opening connecting the test chamber to the loading chamber. A movable gate mechanism has a first position closing the opening and isolating the test chamber from the loading chamber, and a second position wherein the opening connects the test chamber to the loading chamber. A system is connected to the inlet port and the outlet port of the test chamber for supplying a sterilant vapor to the test chamber to establish a sterilizing environment in the test chamber. An indicator holder is operable to move a test indicator from the loading chamber into and out of the test chamber when the gate mechanism is in the second position.

A hydrogen peroxide vapor generation unit () receives hydrogen peroxide and water solution at an interface () and interconnects with an air dryer () by way of nipples (). In one embodiment, the dryer includes a clamping assembly () which is latched () with the nipples and which receives a disposable desiccant cartridge (). In an alternate embodiment, a reusable desiccant cartridge (') is connected directly to the nipples (). When the desiccant cartridge (&#x2032;) is saturated, it is removed and placed in a regenerator unit (). A regenerated cartridge is installed in its place.
