1. Add an appropriate amount of water to the table top steam sterilizer, which should not exceed the specified water level. After adding the water, wrap the instruments that need to be sterilized in kraft paper, and do not put the instruments in directly. This will not achieve the purpose of sterilization. , and for those that need to be filled with culture medium or the bottle needs to be inoculated, use eight layers of gauze to tie the bottle mouth, and then wrap it with kraft paper and put it in for sterilization.

2. Tighten the lid and start heating. When heating, open the exhaust valve. There is a lot of cold air in it that needs to be discharged. If it is not discharged, the temperature will not go up. When heating, pay attention to the temperature and pressure changes. When the temperature reaches 70 degrees, exhaust the air. Turn off the valve and continue to heat up. When it reaches 120 degrees, adjust the power switch, open the exhaust valve properly, and keep the temperature constant.

3. When the table top steam sterilizer reaches the sterilization time, it will start to cool down. When cooling down, you can directly turn off the power and open the exhaust valve slightly. If you want to speed up the cooling, you can wet it with water, but you must unplug the power supply. To avoid electric shock, this is to pay attention to, safety is very important.
