Disclosed is a film canister with an invertible cap having a first side and a symmetrical second side. Each side has oppositely facing circular engagement channels and are each engageable with a body portion that is sized for receiving and containing a roll of film. The first side and second side each have indicia indicative of "EXPOSED" and "UNEXPOSED" respectively to provide a convenient means of identifying the status of a roll of film contained in the canister. The cap is simply engaged on the body portion with the appropriate indicia displayed.

The storage stability of peroxidase-reactive luminescent cocktails which employ chemiluminescent 2,3-dihydro-1,4-phthalazinediones, oxidants reactant therewith to cause light emission in peroxidase-mediated luminescent reactions, and phenolic sensitivity enhancers is improved by maintaining the pH of the cocktail prior to use at a value in the range of about 3 to about 6 and preferably at a pH of about 5. An analyte sample may be subjected to a reaction resulting in a peroxidase-containing phase, the peroxidase content of which is related to the quantity of analyte in the sample, and the peroxidase phase may then be combined with the thus-described cocktail and an aqueous alkaline organic buffer to raise the pH of the resulting reaction mixture to a value in the range of 7-9, favoring light emission.

Methods of impregnating various polymer substrates with an impregnation additive, by simultaneously contacting the polymer substrate with an impregnation additive, carrier liquid, and supercritical fluid are provided. The impregnation additive is substantially insoluble in the supercritical fluid, and the carrier liquid is preferably substantially insoluble in the supercritical fluid.
