• Type 5 chemical integrator for steam sterilization, for use inside every pack
• Black ink reaches 'Pass' area indicates sterilization conditions have been met
• Available with or without extender
• For use in sterilization cycles 250 °F (121 °C), 270 °F (132 °C), 273 °F (134 °C)

Vapor Line® Chemical Integrator is a chemical indicator for monitoring essential conditions of steam sterilization. Vapor Line® AAMI/ANSI/ISO 1140-1 Type 5 integrator, it is designed to show equivalence in performance to biological indicators.

During sterilization, the dark brown/black bar migrates along a paper wick from FAIL into the PASS area, indicating that sterilization conditions were met. PASS results indications that conditions in the sterilized pack were sufficient to kill even the most resistant forms of microorganisms, plus a "overkill period". The 'overkill period' is a safety zone beyond the spore death curve for an additional level of sterilization security.

Vapor Line® is available with or without an extender. The extender acts as an aid for secure sterile presentation. The far end of the extender has a chemical indicator that will react when sterilization conditions are met and change from white to dark brown/black.
