The integrator is designed to show equivalence in performance to biological indicators.
During sterilization, the dark colored bar migrates along a paper wick through PASS and FAIL areas, indicating whether the sterilization conditions were met.
The PASS result assures that conditions in the sterilized pack were sufficient to kill even the most resistant forms of microorganisms plus an "overkill period" - a safety zone beyond the spore death curve for an additional level of sterilization security.
