Chemical integrator sterilisation indicator. For use in steam sterilisation cycles to validate that sufficient sterilisation conditions have been met. The tests consist of a paper wick and a steam and temperature-sensitive chemical pellet in a paper/film and foil laminate. The chemical pellet melts and migrates as a dark colour along the paper wick. Colour migration is visable through a window marked REJECT or ACCEPT. The extent of migration depends on steam, time and temperature. This test is also available with an extender strip affixed to one end of the Comply SteriGage integrator. The affixed extender is a 19cm long rigid, paperboard strip that serves as a handle to retrieve processed integrators from inner packs.
