What Is an EO Sterilizer? Ethylene Oxide Explained
An EO sterilizer uses ethylene oxide gas to sterilize heat-sensitive medical devices at low temperature. Learn how ethylene oxide sterilization works.
Ethylene oxide sterilization is one of the most widely used low-temperature methods for processing heat- and moisture-sensitive medical devices. An EO sterilizer — also written as an ETO sterilizer or ethylene oxide sterilizer — uses ethylene oxide gas to sterilize instruments and devices that high-temperature steam autoclaving would damage.
