Post-sterilization operation

The pressure steam sterilizer in China is required to check the indicator after the sterilized items are dried, and they can be out of the pot when the sterilization requirements are met. When taking sterile items, strict aseptic operation is required. Cover the items first, and close the vent hole of the storage tank. At the same time, they should be sorted and placed, issued and taken sequentially.

Protection against superheated steam

Although the temperature of superheated steam is high, like air, it cannot condense into water and release latent heat when encountering sterilized items, so it is not good for sterilization. The way to prevent overheating is to use external pressure steam sterilizer in china, do not make the temperature of the interlayer higher than the temperature of the sterilization chamber, the two should be similar, do not let the steam with too high pressure enter the sterilization chamber; do not use pressure first when sterilizing High steam is heated to the required temperature and then lowered to normal pressure.

Items that do not deteriorate after autoclaving

Such as sterile water, cultivation medium, and inoculation equipment, can prolong the sterilization time or increase the pressure. The culture medium should strictly abide by the holding time. It is necessary to keep the pressure thoroughly, and prevent the components in the medium from deteriorating or reducing their effectiveness. The time cannot be extended arbitrarily.
