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.

The chemical indicator strips are constructed from special card, standard color patch and indicator strip. The process indicator ink shows clear and accurate color change and indicates if the pack has been processed. These strips are designed for steam, E.O. Gas and plasma sterilization processes.
