3M Attest Rapid Steam Biological Indicator, 1291, Blue Cap
A blue cap rapid biological indicator that monitors gravity displacement steam sterilization at 270 degrees Fahrenheit, providing a fluorescent result within one hour.
The Attest Rapid Steam Biological Indicator, catalog number 1291, Blue Cap, monitors gravity displacement steam sterilization cycles running at 270 degrees Fahrenheit, or 132 degrees Celsius, and is designed to give a much faster readout than the standard 24 hour format. Using a fluorescent detection method, this rapid indicator provides a final result at just one hour after incubation, allowing sterile processing staff to confirm sterilization efficacy and release processed instruments for use far sooner than a traditional biological indicator would allow.
This speed can be particularly valuable in busy central sterile departments where turnaround time for instrument trays affects surgical scheduling. The blue cap colour identifies it within the Attest range as the rapid steam indicator, distinct from the standard steam, ethylene oxide and hydrogen peroxide variants used for other sterilization modalities.
The listing notes that this indicator is transitioning to the equivalent Solventum-branded Attest Rapid Readout Biological Indicator, 1291. It is stocked under a single catalog number.
