  • Tester for peroxide-based compounds
    Patent number: 9068951
    Abstract: An apparatus and a method for the colorimetric detection testing of peroxide-based compositions is disclosed. The apparatus comprises a first carrier having an acidic compound in dry form for hydrolysis of peroxide-based compounds and a second carrier having a colorimetric detection reagent composition in dry form. The carriers are positioned with respect to a support member to facilitate transfer of a solution containing a peroxide-based compound hydrolyzed by the acidic compound when activated into contact with the reagent composition of the second carrier for observation of any resulting color indication. The method comprises steps of applying the acidic compound and colorimetric detection reagent composition is liquid forms to the respective carriers and allowing the applied formulations to dry.
