Ethylene Oxide (ETO) Chemical Indicators are designed to monitor the exposure of medical instruments and packaging materials to the ETO sterilization process. These indicators provide a distinct and irreversible color change upon successful exposure, offering a reliable visual confirmation of the sterilization cycle
Product Description:
ETO Chemical Indicators are used to ensure that the sterilization process conditions have been met inside sterilizer chambers. These indicators are suitable for internal use in instrument trays, pouches, and wrapped items. The color change occurs when all critical variables of the ETO cycle — gas concentration, temperature, humidity, and time — are achieved.
