First, take out the inner bucket of the vertical steam sterilizer china, and then add an appropriate amount of water to the outer pot. When the water surface is at the same level as the triangular shelf, it is enough. I wonder if you noticed this when you poured water. It should be noted that neither the conical flask nor the mouth end of the test tube should be in contact with the barrel wall. This is because we do not want the condensed water to wet the paper at the mouth and penetrate the cotton plug.

Another point, capping, is a common operation in our vertical steam sterilizer china, but during the operation, we often make mistakes, we must insert the capped exhaust hose into the exhaust of the inner barrel in the slot. Then tighten the opposite two bolts at the same time in a two-by-two symmetrical manner, making sure not to leak air.

After the required time is completed, be sure to cut off the power supply or turn off the gas, and let the temperature in the vertical steam sterilizer china drop naturally. At this time, when the pressure of the pressure gauge drops to 0, open the exhaust valve, loosen the bolt, open the cover, and be careful. the removed items. Of course, if you find that the pressure gauge has not dropped to 0, we must not open the exhaust valve, because as long as the exhaust valve is opened, the pressure in the pot will suddenly drop, causing the medium in the container to flush out due to the unbalanced internal and external pressure. The mouth of the flask, which will cause the cotton plug to contaminate the medium and contaminate the medium, then our operation will end in failure.
