Estimation of sterilization time, 1 sterilization in the specific use of how much time, need to be based on the type of items, the size of the package, placement and the performance of the sterilizer to determine.

Pressure steam sterilizer sterilization time calculation, should be calculated from the pressure steam sterilization cabinet room to reach the required temperature, until the sterilization is completed

The total time includes: heat penetration time, that is, from the sterilization cabinet to reach the sterilization temperature to the center of the sterilized items also reached the sterilization temperature required time. At 115 ℃ requires 30 minutes, 121 ℃ requires 12 minutes, 132 ℃ requires 2 minutes. Safety time, generally half of the maintenance time, the length of which depends on the sterilized items. Sterilization of heat-conducting metal equipment does not need to be safe, the length of time depends on the nature of the sterilized items, the size of the package, placed in the location and the degree of air evacuation within the pressure steam sterilization and the type of pressure steam sterilization. Pressure steam sterilizer sterilization maintenance time, that is, the time required to kill microorganisms, generally used to kill thermophilic bacillus lipophilus buds the time required to express,.

Generally under the exhaust pressure steam sterilization time required for: 115 ° C 30 minutes, 121 ° C 15 minutes, 126 ° C 10 minutes. 115 ° C is commonly used in the pharmaceutical industry sterilization. In microbiology laboratories, some sugar-containing media are also sterilized at 115°C for 30 minutes, because sugar decomposes at higher temperatures. 121°C~126°C is commonly used for sterilization in health care and epidemic prevention work.

The above knowledge of the approximate time of sterilization, 1 sterilization in the specific use of how much time, according to the type of goods, the size of the package, placed in the situation and the performance of the sterilizer to determine.
