The sterilization time of China table top steam sterilizer should be calculated from the time when the pressure steam sterilizer chamber reaches the required temperature until the sterilization is completed.

The total time includes: heat penetration time, that is, the time required from reaching the sterilization temperature in the disinfection cabinet to reaching the sterilization temperature at the center of the sterilized item. 30 minutes at 115C, 12 minutes at 121C, and 2 minutes at 132C. The safety time is generally half of the maintenance time, and its length depends on the disinfection items. When the sterilization of heat-conducting metal equipment does not require safety, the length of time depends on the nature of the sterilized items, the size of the package, the placement position, the degree of air emptying in the pressure steam sterilization and the type of pressure steam sterilization. China table top steam sterilizer disinfection maintenance time, that is, the time required to kill microorganisms, is generally expressed by the time required to kill the spores of Thermophilic Bacillus stearatus.

Generally, the required time for exhaust-type pressure steam sterilization is: 115°C for 30 minutes, 121°C for 15 minutes, and 126°C for 10 minutes. 115°C is often used for sterilization in the pharmaceutical industry. In the microbiology laboratory, some sugar-containing media are also sterilized at 115°C for 30 minutes, because sugar will decompose at higher temperatures. 121 ℃ ~ 126 ℃ is often used for sterilization in medical and health and epidemic prevention work.
