Correct operation of autoclave sterilizer
Correct operation of autoclave milk sterilizer is an important premise to ensure the safety of staff.
The correct operation of autoclair machine is an important premise to ensure the personal and property safety of operators. The following are the standard operation steps of autoclair machine arranged by xiaobian for everyone.
1. Take out the autoclave and clean up the impurities in the cavity. Before use, please refer to the autoclave manual carefully.
2. Place the autoclave in a stable and safe place, screw the manual drainage valve to the “off” place, add distilled water (more than 1OL as usual) into the sterilizer, add water slowly, so as not to add too much water and affect the normal operation of the instrument, until the high water level is on, add 1 ~ 2L more.
3. Temperature and time can be set according to specific sterilized items. The specific operations are as follows:
Press the “Set” button, and the temperature setting will be displayed. You can press the up and down arrow keys to set the desired value. In the same way, you can set the sterilization time.
Sterilization operation requirements of autoclave for different sterilized items:
Put the sterilized items into the chamber and put them neatly. It should be noted that the height of the items should be lower than the chamber to avoid blocking the top exhaust valve and causing danger. Different sterilization methods and time are different, special attention should be paid to the sterilization of dressings, dressings are installed in stainless steel machine dishes, most users forget to open the ventilation hole of dressing box, so that each sterilization can not reach the color of the strip, resulting in sterilization failure. The sterilization of some instruments is tied with cloth belt sterilization, after sterilization, do not open the packaging of cloth belt, otherwise it will be contaminated again.
When sterilizing liquid and culture medium, note that when sterilization is completed, the autoclave must be cooled by natural exhaust. It is not allowed to let air out quickly and cool rapidly, so as not to cause the glass container to burst due to sudden temperature changes, thus threatening the safety of the experimenter and causing autoclave pollution.
Cover the sterilized items with a layer of cloth, so that the sterilized items will not worry about the sterilization effect due to humidity. Try to let the autoclave cool naturally, and do not open the safety valve and exhaust valve above, so as not to cause the danger of high pressure gas injury. It is recommended to open the safety valve and exhaust valve above the autoclave once a month to avoid the danger of rust and rust death.
4. Tighten the door cover and screw the manual exhaust valve under the autoclave to the appropriate position of exhaust to facilitate the uniform temperature of the gas in the cavity. At this time, the chain switch is closed, the chain light is on, and the instrument starts to work.
