The ethylene oxide(EO) sterilizer is used to sterilize items that are sensitive to heat and humidity and all items that cannot be autoclaved. The ethylene oxide sterilizer must meet the following conditions, such as water, electricity, and steam (ethylene oxide gas, compressed air) before the sterilization process can be performed. Ethylene oxide has good bactericidal power to various microorganisms, has strong penetrability, and does little damage to articles. Ethylene oxide, also known as "ethylene oxide", is a colorless and transparent liquid with the smell of ether.

   Gaseous ethylene oxide is flammable and explosive, and should be kept in special ampoules or pressure-resistant metal cans. The ethylene oxide sterilizer should be installed in a sterile environment, close to the compressed air. Exhaust fans should be installed in this environment to remove the ethylene oxide gas dispersed in the air in time. Items sterilized with ethylene oxide must be packaged with special standard paper and plastic. Put an indicator card in the bag. The disinfection date is generally 1-2 years. Such as disinfection of various items, especially various pipes, must be dry to prevent the sterilization effect from failing due to water. It is strictly forbidden to use ethylene oxide sterilizer to sterilize oily items. Because the purpose of sterilization is not achieved.
