Chemical Ethylene Oxide Indicators
Chemical ethylene oxide (EO) indicators undergo a significant colour change from violet (unexposed) to green when exposed to EO gas. The shade of green depends on the sterilization conditions used, e.g.: EO concentration, gas-mixture, sterilization time, preconditioning, temperature, relative humidity and steam-injection. Chemical EO indicators are meant to be used on individual items that need to be sterilized. The indicators can be supplied as single dots, squares or other shapes They can be printed or applied to larger labels that are preprinted or customized with text or company logo.

Biological Ethylene Oxide Indicators
Biological ethylene oxide (EO) indicators are carriers with spores of bacillus atrophaeus, as a challenge to the sterilization process. They are used for validation and routine monitoring to demonstrate the efficacy of the sterilization cycles. The indicator is exposed to the process and then incubated under defined growth conditions to determine whether any spores survived the process. If no spores survive, none grow and the cycle is a pass. If growth is detected, it is a fail. All Etigam biological indicators rely on true and full microbial growth. A dedicated reader is not required, the result can be visually verified (by colour-change or turbidity).
