The rapid development of medical technology has gradually promoted the application of various precision instruments and equipment, and these equipment often cannot be sterilized due to their inability to withstand high temperatures. In order to solve this problem, various low-temperature sterilization methods have gradually emerged, such as ethylene oxide (EO) low-temperature sterilizer, hydrogen peroxide plasma (plasma) sterilizer, low-temperature steam formaldehyde sterilizer (LTSF), It is widely used clinically.
