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

Sterilant challenge device for a sterilization monitoring system

A drive-out assembly to thread a film wound on a reel or in a coil 2 includes an arm 7 to swing into the cartridge and engage the film with a drive-out roller 8 which drives the film in an unwinding direction to drive the free end over a stripper member 10 urged against the film. The drive for the drive-out roller 8 includes a first drive gear 20 which rotates a driven gear 23 through an intermediate gear 21 to drive a shaft 19 having a drive gear 23 to drive the drive-out roller 8 through other intermediate gears 24, 8'.
