Abstract: The disclosed sterilization monitoring device comprises a perfusion channel with a chemical indicating composition disposed in fluid communication with the perfusion channel. Exposure to a sterilant creates a laterally moving front across the chemical indicating composition in the perfusion channel.

Abstract: The disclosed multilayer test pack comprises a channel lamina to form a recessed channel, and then a seal layer covers the recessed channel to form an embedded channel By providing the recessed channel in a thin-film channel lamina, the recessed channel tolerances are better controlled. Further, using thin films for the channel lamina, which can be formed into a roll, allows for a continuous unrolling and continuous bonding to a seal layer.
