Product Overview
The EO Indicator Strip is an internal chemical indicator for ethylene oxide sterilization. It is placed inside pouches, packs or cartons and responds to the combination of EO gas concentration, relative humidity, temperature and exposure time, changing from red to blue when the stated values are reached.
Together with EO indicator tape on the outside of the pack and biological indicators for load release, it forms a complete EO monitoring system for hospitals and device manufacturers.
