Sterilant challenge device for a sterilization monitoring system

A sterilant challenge device (1), for use in testing the efficiency of the air removal stage of a sterilization cycle in a sterilizer, includes a tube (2) of thermally-insulating material, the bore of which is closed at one end (3) and open at the other for the entry of sterilant. A plurality of the...

More Information
Summary:A sterilant challenge device (1), for use in testing the efficiency of the air removal stage of a sterilization cycle in a sterilizer, includes a tube (2) of thermally-insulating material, the bore of which is closed at one end (3) and open at the other for the entry of sterilant. A plurality of thermally-conductive masses (4) is located around the tube (2) and thermally-separated from one another by air gaps (14), and a temperature sensor is located in an opening (16) in one of the masses adjacent the closed end of the tube. An outer casing (5) defines an air space around the thermally-conductive masses and thermally insulates the masses from the heat in the sterilizer.
