The SQ-E series sterilizer has the characteristics of sophisticated design and high technology. It consists mainly of a microprocessor control system, a gas residue treatment device, a sterilization chamber and other parts. The principle of operation is to use ethylene oxide gas, which, in a certain state of sterilization, achieves the desired effect under humidity pressure. Ethylene oxide destroys microbial proteins, interferes with their metabolism and kills resistant bacilli.
