Abstract
A device useful in determining the efficacy of a chemical sterilization process includes a dead end cavity closed by an access cap having a port coupled to a challenge tube defining the only path by which a substantial quantity of sterilant can reach the cavity. A biological indicator is located within the cavity and a chemical indicator is also provided. These indicators, and particularly the biological indicator, provide an indication of whether chemical sterilant would reach all interior exposed surfaces of a load in sufficient concentrations to adequately sterilize the load.
