Chemical Indicators for Sterilization

What are Chemical Indicators?

Chemical indicators are used to monitor whether the parameters to achieve sterilization have been met for a specific sterilization process, such as steam or vaporized hydrogen peroxide sterilization. Chemical indicators use one or more chemicals that undergo either a physical or chemical change that is visible to the human eye after exposure to predetermined critical parameters like temperature, time or sterilant.

STERIS’s complete portfolio of chemical indicators includes both internal and external indicators. Internal chemical indicator strips and challenge packs are used to capture sterilization failures through immediate results, while external indicator tapes and labels confirm a pack has been exposed to the sterilization process.
