Self-Contained Biological Indicators consist of:
✅ A plastic pipe and cap. The cap with a hole is placed on top of the pipeto allow the sterilizing agent to penetrate into the indicator. Between pipe and cap there is a filter paper which is used to avoid pollution.
✅ A crushable media ampule which contains modified culture mediumwith a pH indicator and fluorogenic substrates. The modified culture mediumwill transition from the initial Purple color to Yellow in the presence of bacterial growth.
✅ An inoculated carrier of Geobacillus stearothermop hilus ATCC 7953 is located at the bottom closed end of the pipe.
✅ A barrier is positioned like a plug between the carrier and the ampule.
✅ The LBS180 Biological Indicator, when used with an automatic reader(incubation temperature 56-60°C), provides a fluorescence test result in a short period(180 minutes) with an accuracy of ≥97%. As an option the user can continue the incubation for 48 hours in order to confirm visually the stability or color change of the culture medium.
✅ The label on the outside of the plastic pipe contains a Type 1 chemical indicator strip.
