Introduction to Medical EO Gas Sterilizer
A Medical EO Gas Sterilizer uses ethylene oxide to sterilize devices that cannot tolerate steam or high moisture. It provides deep penetration through packaging and complex geometries, making it suitable for polymers, electronics, and multi-component instruments. Validated cycles help healthcare providers and manufacturers achieve reliable sterility assurance for critical care products.
Working Principle and Process Flow
Devices are cleaned, dried, and packaged in breathable materials. The chamber performs pre-conditioning to achieve target temperature and humidity. EO gas exposure follows, inactivating microorganisms at the surface and within lumens. Finally, aeration removes residual EO to safe levels. Continuous monitoring and documentation support compliance and repeatability.
