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. The carriers are then positioned with respect to a tester 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. When a test is to be performed the formulations are activated by water, and a composition to be tested is placed in contact with the carriers and any color change of the colorimetric detection reagent is observed.

Tester for peroxide-based compounds

A trash container includes a bottom receptacle with a hinged lid. The hinge connection makes hinge opening(s) along the hinge axis. A trash bag in the receptacle, which extends up and over the sides of the receptacle, includes upward-extending back tab(s) for placement through the hinge opening(s). A removable elastic band fits around the receptacle below the lid to secure the bag and tabs in place in the receptacle.
