Information

In the airtight table top steam sterilizer, the steam cannot escape, and the pressure continues to rise, so that the boiling point of the water continues to increase, so the temperature in the pot also increases. Under the pressure of 0.1MPa, the temperature in the pot reaches 121℃. At this steam temperature, a variety of bacteria and their highly heat-resistant spores can be quickly killed.

Only when the air in the table top steam sterilizer is completely removed, so that all the water vapor in the pot can be completely sterilized. There are several different methods of high-pressure sterilization and air release, but the purpose is to exhaust the air, make the temperature in the pot evenly, and ensure complete sterilization. The common method is to close the air release valve. After the power is turned on, when the pressure rises to 0.05MPa, open the air release valve and release the air. After the pointer of the pressure gauge returns to zero, close the air release valve. After closing the valve and then energizing, when the pressure gauge rises to 0.1MPa, start timing and maintain the pressure at 0.1-0.15MPa for 20 minutes.

After the pressure holding time is reached, the power supply can be cut off. When the pressure drops to 0.5MPa, the steam can be released slowly. Care should be taken not to reduce the pressure too fast, causing intense decompression boiling and overflowing the liquid in the table top steam sterilizer. . When the pressure drops to zero, the lid can be opened, the medium is taken out, and placed on the platform to wait for condensation. Do not deflate for a long time, causing changes in the composition of the medium, so that the medium cannot be tilted. Once placed for too long, the lid cannot be opened due to the negative pressure in the boiler. As long as the air release valve is opened, the atmospheric pressure is entered, and the internal and external pressures are balanced, and the lid can be easily opened.

Anti-bedsore mattresses in China can be inflated immediately after purchase, but it is best to use them 12 hours after the first inflation is completed 8 hours later. Because anti-bedsore mattresses in China need a cushioning process for the inner straps and seams, try not to inflate the new anti-bedsore mattresses in China 2 days before use.
