Chemical Indicators for Sterilization

What are Chemical Indicators?

Chemical indicators monitor whether the parameters to achieve sterilization have been met for a specific sterilization process, such as steam or vaporized hydrogen peroxide sterilization. After exposure to predetermined critical parameters like temperature, time, or sterilant, chemical indicators undergo physical or chemical changes visible to the human eye.

STERIS offers a variety of chemical indicators for use in steam sterilization, low-temperature sterilization (including both V-PRO® or STERRAD™*), and challenge packs. Browse available chemical indicators based on indicator Type (previously known as Class), standard cycles, and product features.
