E ylene Oxide (EtO) is a common gas used for low temperature sterilization. It is a colorless, poisonous gas at attacks e cellular proteins and nucleic acids of microorganisms. It is most commonly used to sterilize instruments wi long lumens such as endoscopes and all materials at have to be sterilized but cannot wi stand higher. E ylene oxide gas(EOG) sterilization procedure was regarded as e last candidate of sterilization pro-cedure due to toxic gas residue. e most recommend-ed sterilization procedure is autoclaving, if e medical device is not sensitive to e heating. Because moist heat sterilization procedures are simple and no toxic residues. E ylene oxide (EtO) sterilization is a chemical process consisting of four pri y variables: gas concentration, humidity, temperature and time. During is process, EtO acts as an alkylating agent, effectively disrupting e DNA of microorganisms to prevent em from reproducing, ultimately resulting in sterile products suitable for medical use. E ylene Oxide E ylene oxide (EtO) sterilization is a commonly used sterilization technique used to sterilize items at are heat or moisture sensitive.

Gas is pumped out for 2 minutes and en fresh air in for 2 minutes for e whole duration of e aeration period, ensuring at when e steriliser is opened by e operator exposure is below limits. E ylene oxide, called oxirane by IUPAC, is an organic compound wi e formula C 2 H 4 O.It is a cyclic e er and e simplest epoxide: a ree-membered ring consisting of one oxygen atom and two carbon atoms.E ylene oxide is a colorless and flammable gas wi a faintly sweet odor. Because it is a strained ring, e ylene oxide easily participates in a number of addition reactions at Chemical formula: C₂H₄O. E ylene oxide (EtO) is produced in large volumes and is pri ily used as an intermediate in e production of several industrial chemicals, e most notable of which is e ylene glycol. It is also used as a fumigant in certain agricultural products and as a sterilant for medical equipment and supplies. Chat Instructions.
