Biological Indicator (Bionova BT20) for Autoclave Sterilization Validation:Introduction, Application, and Keynotes

by
These Bionova BT20 biological indicators are used to monitor the effectiveness of steam sterilization (autoclave) cycles. Each vial contains a spore suspension of Geobacillus stearothermophilus in a nutrient medium with a pH indicator dye. The purple vial indicates successful sterilization (no spore growth-left vial).The yellow vial indicates failed sterilization (spore germination and acid production changing the color to yellow-right vial).

Introduction Bionova BT20 Biological Indicators (BIs) are specialized tools used to verify the efficiency of steam sterilization (autoclaving) in laboratories, hospitals, and industrial settings. Each indicator vial contains a defined population of Geobacillus stearothermophilus spores, known for their high resistance to moist heat. During an …
