Scope And Conditions Of Gas Sterilization

Ethylene oxide, also known as ethylene oxide, is a colorless liquid at low temperatures with an aromatic ether smell, a boiling point of 10.8°C, an odor threshold of 760 mg/m~1064 mg/m, and a density of 1.52; ethylene oxide is flammable and explosive, and its minimum combustion concentration is 3%. Ethylene oxide gas has strong penetrating power.
Ethylene oxide gas has strong bactericidal power and a wide spectrum of bactericidal activity. It can kill various microorganisms including bacterial spores and is a sterilant.
Scope of application
Ethylene oxide does not damage sterilized items and has strong penetrating power. Therefore, most items that are not suitable for sterilization by general methods can be disinfected and sterilized with ethylene oxide. For example, electronic instruments, optical instruments, medical devices, books, documents, fur, cotton, chemical fibers, plastic products, wood products, ceramics and metal products, endoscopes, dialyzers, and disposable medical supplies. Ethylene oxide is one of the most important low-temperature sterilization methods.
Conditions of Use
There are many factors that affect the sterilization of ethylene oxide gas. Only by strictly controlling the relevant factors can the sterilization effect be achieved.
