ABSTRACT:
A biological indicator is disclosed for determining the efficacy of a sterilization cycle using hydrogen peroxide vapor at subatmospheric conditions. The biological indicator includes a vial formed of a substance which resists retention of residual sterilant while also maintaining vial clarity. Also disclosed is an improved cap design which facilitates activation of the biological indicator after the sterilization cycle is complete.
