Chemical Indicators are used to be certain that packs are having totally included, and adequately penetrated with steam. You will find standard chemical indicators, and there is chemical indicator tape.
If the results of the repeat spore exam is negative and operating methods were accurate, then the sterilizer could be returned to services.
