Ethylene oxide, also known as ethylene oxide, is a colorless liquid at low temperature, with aromatic ether flavor, boiling point of 10.8 ℃, olfactory threshold of 760 mg / m-1064mg / m, density of 1.52; ethylene oxide is flammable and explosive, with a minimum combustion concentration of 3%. Ethylene oxide gas has strong penetration.
Ethylene oxide gas has strong bactericidal power and wide bactericidal spectrum, which can kill all kinds of microorganisms, including bacterial spores. It is a bactericide.
Applicable scope of gas sterilization
Ethylene oxide does not damage the sterilized articles and has strong penetration, so most articles that are not suitable for general sterilization can be sterilized and sterilized with ethylene oxide. For example, electronic instruments, optical instruments, medical devices, books, documents, fur, cotton, chemical fiber, 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.
Use method of gas sterilization
Because ethylene oxide is flammable, explosive and toxic to people, it must be carried out in a closed ethylene oxide sterilizer.
Use conditions of gas sterilization
There are many factors that affect the sterilization of ethylene oxide. Only by strictly controlling the relevant factors can the sterilization effect be achieved.
Today, it has become a world leader in 100% ethylene oxide gas (EO) sterilization, making it safer, more reliable, more convenient, more economical, and more environmentally friendly. 3M has been a 100% EO supplier since 1965, offering different sizes depending on the size of the hospital. The entire sterilization process is completely in a negative pressure state to ensure that the gas does not leak out. The built-in temperature probe can adjust the temperature immediately. The built-in humidity probe ensures relative humidity> 65%. The built-in exhaust device completes the highly intelligent control of sterilization and exhaust. Computerized operation. Obtained UL, TUV, CE, CSA agency test box evaluation requirements. Helps you control load and turnaround time to meet peak usage needs. Multiple installations allow simultaneous sterilization and automatic venting. Embedded wall mounting and freestanding shelves can install multiple sterilizers at the same time, saving time and effort, and saving space. The world's first 100% EO gas single-dose gas tank manufacturer.
