Sterilization

Why Ethylene Oxide?

There are many benefits to ethylene oxide sterilization, some of which may be crucial to your hospital or clinic, especially when reprocessing complex multi-channel endoscopes and delicate medical devices. Andersen’s FDA-cleared sterilizers offer several advantages, including low per-cycle cost, low-temperature operation and EO-Flexible Chamber Technology, which allows our systems to use a microdose of EO — just 17.6 grams per cycle. Our systems are able to achieve terminal sterilization (10-6 SAL) with 90% less EO than our competitors — this is ethylene oxide sterilization reimagined.
