Comparing EO to Other Modalities
Andersen Sterilizers’ low-temperature systems feature award-winning EO-Flexible Chamber Technology,® which requires only a microdose of ethylene oxide (EO) — just 17.6 grams or one and a half tablespoons per cycle. Ethylene oxide is powerful and effective but also gentle and compatible, which means our systems can sterilize a wide range of devices and materials. Our FDA-cleared systems are compatible with nearly all medical devices and present minimal risk to operating personnel when used according to safety protocols. Ethylene oxide sterilization is a proven option for healthcare facilities handling complex or delicate instruments. But how does EO compare with other sterilization/HLD methods? Take a look at the chart below.
At-A-Glance

Ethylene oxide offers unique advantages in versatility and compatibility, especially for heat- and moisture-sensitive medical instruments. Ethylene oxide achieves a Sterility Assurance Level (SAL) of ≤ 10⁻⁶ at low temperatures. While methods like steam sterilization and hydrogen peroxide plasma are also highly effective and well-suited for many applications, they may have limitations with certain materials or device designs. Ethylene oxide complements these modalities by providing a proven sterilization option for instruments that may not be compatible with other systems, helping you to protect your most vulnerable patients.
