What is a Chemical Indicator?

Chemical indicators are a device designed to respond with a chemical or physical change to the presence or attainment of one or more of the physical conditions within the sterilizing chamber.

 

Chemical Indicators and Sterilization Validation

Chemical indicators are used to quickly identify equipment or process failure. Get immediate confirmation that items have been exposed to a sterilization cycle.

 

ANSI/AAMI ST79 states,

“Chemical indicators verify that one or more conditions necessary for the sterilization have been achieved within the package and/or specific location within the load. Biological indicators verify that the conditions at a location within the load were adequate to kill a population of microorganisms resistant to the sterilization process and demonstrate the lethality of the sterilization process.”
