An EO Sterilizer (Ethylene Oxide Sterilizer) is a medical sterilization system used to sterilize heat-sensitive and moisture-sensitive medical devices, such as syringes, infusion sets, catheters, tubing, and plastic components. It is widely used in the medical device and pharmaceutical industries.
The EO sterilization process uses ethylene oxide gas under controlled conditions of temperature, humidity, gas concentration, and exposure time to destroy microorganisms, including bacteria, viruses, spores, and fungi. Because the process operates at low temperatures, it is ideal for products that cannot withstand steam or high heat.
An EO sterilizer typically consists of a sterilization chamber, vacuum system, gas injection system, heating and humidification system, control system, and exhaust/aeration system. After sterilization, products undergo an aeration phase to remove EO gas residues and ensure safety for clinical use.
EO sterilizers offer advantages such as deep penetration, high sterilization reliability, wide material compatibility, and compliance with international medical standards. They play a critical role in ensuring product sterility, safety, and regulatory compliance in disposable medical device manufacturing.
