3M Attest Steam Biological Indicator, 48 Hour Readout
A 48 hour readout biological indicator that monitors gravity displacement and vacuum assisted steam sterilization processes for industrial and life science use.
The 3M Attest Steam Biological Indicator, brown cap, is designed to monitor steam sterilization processes run under gravity displacement conditions at 250 degrees Fahrenheit and vacuum assisted conditions at 270 degrees Fahrenheit, giving a final visual colour readout after 48 hours of incubation. It is intended specifically for monitoring pharmaceutical and industrial, or life science, steam sterilization processes, which tend to follow validated cycle parameters distinct from routine hospital sterile processing.
The longer 48 hour incubation period reflects a traditional biological indicator format, offering a thorough, well established confirmation of spore kill for facilities where speed is less critical than a fully validated result. This row includes a sterile variant option alongside the standard model, giving buyers a choice depending on whether a pre-sterilized indicator is required for their monitoring protocol.
These indicators are used by quality assurance and microbiology staff in pharmaceutical manufacturing sites, industrial sterilization facilities and life science laboratories responsible for validating and routinely verifying steam sterilization cycle performance.
