Dry Heat Biological Indicator
SteriVision Dry Heat Biological Indicator is designed to provide microbiological verification of dry heat sterilization cycles used in healthcare, laboratory, and industrial settings. The self-contained indicators can be positioned directly among loads, inside packs, or at locations considered most difficult for heat to reach. Their robust glass ampoule and protective plastic vial construction helps maintain integrity throughout processing while providing clear evidence that the required time and temperature conditions have been achieved.
Each indicator contains viable Bacillus atrophaeus (ATCC 9372) spores, selected for their high resistance to dry heat. After exposure, the internal ampoule is activated and the indicator is incubated for 48 hours. A visible color response in the growth medium indicates whether microbial growth is present, enabling personnel to distinguish a successful cycle from a potential sterilization failure and document the result with confidence.
Key Benefits and Features
Place the indicator directly inside the dry heat sterilizer, between instruments or packs, and at the most challenging points of the load without disrupting routine workflow.
Highly resistant Bacillus atrophaeus spores provide direct microbiological evidence of the cycle’s ability to inactivate resistant microorganisms.
Following 48 hours of incubation, the color of the growth medium provides an easy-to-interpret indication of cycle performance.
Reliability and Traceability
Complete Traceability: Each indicator label carries reference (REF), lot (LOT), and expiry (EXP) information to support accurate documentation and retrospective tracking.
International Standard: Designed for use in ISO 11138-aligned sterilization monitoring and quality assurance programs.

Construction and Practical Advantages
Highly Resistant Spores
Bacillus atrophaeus spores, recognized for their resistance to dry heat, provide a demanding biological challenge for reliable cycle monitoring.
Activatable Glass Ampoule
The internal glass ampoule can be activated after processing to create a closed, self-contained incubation environment.
Readable Result in 48 Hours
After the prescribed incubation period, the growth medium provides a clear visual result for routine interpretation.
High-Temperature Construction
The protective outer vial is designed to withstand dry heat cycles at 160°C and above.
Intended Use: Routine microbiological monitoring of dry heat sterilization cycles to verify that processing conditions are sufficient to inactivate resistant spores.
