Instructions for bactericidal biological indicators of Bacillus subtilis

Model: Bacillus subtilis sterilization biological indicator

Scope of application: for biological monitoring of sterilization effect of ethylene oxide sterilizer

说明 Product description: This product is a biological indicator for sterilization of ethylene oxide. The survival time of spore resistance of Bacillus subtilis black variant is 15 minutes or more, and the killing time is 60 minutes or less.

How to use: Put the indicator in a standard test package. According to national regulations, place each test package in a different position in the pot. After the sterilization process is completed, remove the biological indicator, squeeze out the contained ampoules, and The control tube was placed in a 37 ° C incubator. After 48 hours, read the results: the sterilization tube does not change color (green), indicating that the sterilization has passed; the sterilization tube changes color (yellow), indicating that the sterilization has failed. Simultaneous cultivation Control tube should be positive (yellow)

How to read: After culturing, the sterilization tube does not change color (green), indicating that the sterilization has passed; the sterilization tube changes color (yellow), indicating that the sterilization has failed; (the reason for the sterilization failure must be found in time). The control tube cultured at the same time should be positive (yellow), if negative, the possible reasons are: the culture conditions do not meet the requirements, the biological indicator problem (the negative cause should be found in time)

How to discard: Positive indicator, discard after ethylene oxide sterilization

  Production Date:

Validity period: 24 months from the date of production

Storage method: Store at room temperature 15-30 degrees, relative humidity 35-60%. Avoid close to sterilization and chemical disinfectants

Note: The biological monitoring results can only be valid if the control tube is positive

Recommended use; It is recommended that each pot should be tested with a biological indicator to assess the quality of the entire load sterilization.
