EO sterilization refers to ethylene oxide sterilization. Ethylene oxide sterilization device is the key equipment for single-use sterile medical device manufacturers, installation, operation, use and management of its special requirements, the use of ethylene oxide as a sterilizing agent, ethylene oxide is a broad-spectrum sterilizing agent, which can kill a variety of micro-organisms, including spores, tuberculosis bacilli, bacteria, viruses, fungi, at room temperature.
Ethylene Oxide Sterilization Overview
Currently, ethylene oxide is widely used in medical devices to sterilize . Ethylene oxide is flammable and explosive toxic gases, molecular formula for CHO, with an aromatic ether flavor, in 4 ° C when the relative density of 0.884, boiling point of 10.8 ° C, its density of 1.52 g / cm, at room temperature, it is easy to volatile gas, when the concentration is too high can cause an explosion.
The advantage is that it kills all microorganisms, including bacterial spores. Sterilized items can be wrapped, encapsulated as a whole, and can remain sterile until used. EO is relatively non-corrosive to plastics, metals and rubber, and does not cause items to become yellowed or brittle. Penetrates and sterilizes irregularly shaped items. Can be used for those who can not be sterilized by disinfectant immersion, dry heat, pressure, steam and other chemical gas sterilization of the goods.
