There are many types of sterilizers seen on the market, and the quality of the sterilizer is also uneven, so everyone should test when purchasing sterilizers, what sterilizer is the best Below we will give you a simple introduction to the effect of the sterilizer is the best.
Both the Bacillus tips were placed in a sterile tweezers.
Chemical instruction card and point in the test tube of the spot temperature meter.
The two test tubes were prepared for 5-10 parts.
Placed at the sterilizer steam mouth, at the bottom exhaust port and the bottom of the bottom of the bottom or down.
If the pressure steam sterilizer is two, it is necessary to put 10.
After the point of temperature, you can use it to verify the test.
Pre-detection, the mercury column of the thermometer is required to 40 ° C or lower.
The temperature difference of the dot point temperature meter should be between 1 ° C after each monitoring, then the temperature distribution in the sterilizer is uniform.
The sterilized bacteria should be in the rigorous sterilization of bromol mexhydramidum culture medium under strict sterile operation.
56-60 ° C culture for 24-48 hours, and the color changes were observed.
If the medium is changed to yellow, it is not completely inactivated by the Bacillus Bacillus in the ps., and the bacteria can still grow in the medium, and the decomposition of glucose has become yellow.
If the medium color does not change is still purple, the spacospore has been inactivated.
At the same time, it was used as a positive control in a positive control, and the blank medium without paper sheet was used as a negative control.
The indication color block on the chemical indicator is sterilized in sterilizer, which is changed from light yellow.
As the color changes, it can determine whether the sterilization effect is required to meet the requirements as compared with the control color. The chemical indicator card should be stored in a dry place.
The champion will discharmatically, affect the observation of the sterilization effect.
The sterilizer must make the steam into the sterilizer, contact with the sterilized item, and the original cold air discharge can achieve the effect of sterilization.
It is necessary to perform an air-load thermal distribution and full load of thermal penetration verification (2/3 of the total volume is not exceeding the total volume). Two validations were repeated three times and a total of six tables.
The 5-point test showed that the temperature was 121 ° C, the chemical indication card turned black; the degree was consistent with the control color; the medium did not change color, indicating that the sterilizer effect is qualified.
The above test method is a relatively professional method. When doing more tests, the material required for the material has some material of Bacillus, Bacillus, Bacillus, and the pressure steam sterilization instruction card.
