The Attest Biological Indicator is a small vial
containing a quantity of non-pathogenic spores
especially resistant to the steam sterilisation
process. Following the sterilisation cycle, the
ampoule within the vial is crushed, providing
media that will promote rapid growth of any
spores that may not have been killed during the
sterilisation process. An easily detected colour
change in the vial after incubation indicates the
sterilisation process has failed.
