Ethylene oxide chemical indicator strip Comply

3M Comply 1251 Ethylene Oxide Chemical Indicator Strips provide immediate visual confirmation of EO sterilization exposure for veterinary instruments and packs. The internal strip changes from red to green when exposed to critical parameters—gas concentration, relative humidity, exposure time, and temperature. Compatible with warm and cold cycles of 100% ethylene oxide gas and EO/hydrochlorofluorocarbon systems, each strip is easy to place and read. Sized at 1.5 cm x 20 cm (0.625 in x 8 in), this 240-strip box supports efficient workflow in veterinary clinics and animal hospitals.
