The VERIFY Spore Test Strip for S40 Sterilant Concentrate is intended to provide users with a means to assess spore kill by S40 Sterilant use dilution in the STERIS automated Liquid Chemical Sterilant Processing Systems (SYSTEM 1E and SYSTEM 1 endo Liquid Chemical Sterilant Processing Systems and enspire 3000 Series Cleaning and Liquid Chemical Sterilant Processing System). A “no growth” result from the VERIFY Spore Test Strip for S40 Sterilant Concentrate after 24 hours of incubation indicates that the liquid chemical sterilization process achieved the conditions necessary to kill at least 1 x 105 viable spores (5 logs) on the spore test strip (STS). It does not confirm the expected full performance of the liquid chemical sterilization cycle.
Indications for use as stated in the FDA summary.
