40-50℃.
Medical institutions can choose different sterilization methods in accordance with the nature of the sterilized items: for moisture-resistant, heat-resistant diagnostic and therapeutic instruments, appliances and items, pressure steam sterilization should be preferred, for heat-resistant oils and dry powders, etc. should be used dry powder sterilization.
Non-heat-resistant, non-humidity-resistant items, it is appropriate to use low-temperature sterilization methods, such as ethylene oxide sterilization, hydrogen peroxide low-temperature plasma sterilization or low-temperature formaldehyde steam sterilization.
Extended information
Currently the world's mainstream hospitals use low-temperature disinfection sterilization techniques such as glutaraldehyde, acidified water, peroxyacetic acid, ethylene oxide sterilization, hydrogen peroxide low-temperature plasma sterilization, low-temperature steam formaldehyde sterilization.
Hydrogen peroxide plasma is a new low-temperature sterilization technology began to emerge in the 1990s. Plasma is considered to be the fourth state in addition to liquid, gas, and solid, and is formed when gas molecules are excited in a cavity of extreme vacuum.
Hydrogen peroxide plasma sterilization has the advantages of a short sterilization cycle time and low toxicity of the thoroughly decomposed end products. However, due to the consideration of Mycobacteria tuberculosis contamination, the U.S. FDA has not yet approved the use of diffusion enhancers to solve the problem of hydrogen peroxide vapor penetration of long and narrow lumen items difficult.
