Ethylene oxide sterilization principle

    Ethylene oxide gas has the characteristics of strong penetrability, broad spectrum of sterilization, thorough sterilization, no corrosion and damage to articles. By alkylation with the thiol (-SH), amino (-NH2), hydroxyl (-OH) and carboxyl (-COOH) on protein molecules and imino (-NH2) on nucleic acid molecules, proteins are forced to lose the reactive group, blocking normal biochemical reaction and metabolism. Accordingly, microbes die and the sterilization effect can be achieved.

Full-automatic sterilizer

Criteria for implementation：

1.   YY0503-2016《Ethylene oxide sterilizer》；
