Low Temp Steam Formaldehyde Sterilization Rapid Biological Indicator (0.5h)


Application of Rapid Biological Indicator:

This product uses Thermophilic Fatty Bacillus spores (ATCC7953) as indicator bacteria, consisting of bacterial tablets, recovery medium (loaded in ampoules), and a plastic shell. By detecting the activity of a-glucosidase and reflecting the survival of spores of thermophilic fatty acid bacteria, it is determined whether low-temperature steam formaldehyde sterilization is qualified. The rapid biological indicator can be used in conjunction with the corresponding biological reader to read the biological monitoring results of the sterilization process within 0.5 hours.

Usage method:

  1. Place this product in a standard test bag or a paper plastic packaging bag in the package to be sterilized as required, and place it in the most difficult sterilization position in a low-temperature steam formaldehyde sterilizer. Load it normally and run the sterilization program.

  2. After sterilization, remove the biological indicators from the packaging bag. After confirming that the color of the chemical indicator on the label of the biological indicator has changed from red to yellow, place it and cool it to room temperature. Press down on the indicator cover to close the side vent hole of the cover, and use a dedicated card slot on the reader to squeeze the indicator plastic tube to break the ampoule bottle inside the plastic tube. Confirm that the bacterial tablet fully contacts the culture medium, insert it into the high-speed reader and cover the reader cover for cultivation, and wait for the corresponding culture hole of the reader to send a result signal.

  3. Take another unsterilized biological indicator of the same batch number and crush the ampoule bottle according to the previous method, and use it as a positive control for cultivation under the same conditions.

  4. For the biological indicators for culture detection, the culture medium ampoule bottle should be broken and placed in a reader for cultivation within 2 minutes.

  5. The detection time of this product in the high-speed reader is 0.5 hours.

Result determination:

Qualified: For the indicator after sterilization, fluorescence negative (or -)

Unqualified: For the indicator after sterilization, fluorescence is positive (or +)

The above two results are only valid for this biological monitoring if the positive control shows fluorescence positive results.
