The removal of moisture from an object to be sterilized is provided through at least the steps of placing the load in the chamber, reducing the pressure within the chamber to increase the rate of evaporation of moisture from the load, monitoring over a predetermined period of time the increase in the quantity of vapor within the chamber resulting from evaporation of moisture from the load, admitting gas into the chamber and repeating the steps following placing the load into the chamber.

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.

Accurate measurements of the concentration of a sterilant in a sterilization chamber are provided through the use of a light source, a first detector that receives light from the light source that has not passed through the sterilization chamber and a detector that receives light from the light source that has passed through the sterilization chamber. The light contains wavelengths known to be absorbed by the sterilant. A controller receives and processes signals received from the two detectors to cancel changes in the output of the light source and then apply a modified Beer-Lambert law to determine the concentration of the sterilant gas.
