Description
Oil Red O is a chemical latent print developer that answers a long-standing problem —how to develop latent prints on paper products that are wet or have been wet. Other chemical processes such as Ninhydrin, DFO and Physical Developer have proven to be ineffective under these circumstances. ORO is a lipid protein stain used in biological research and, when used in forensic applications, it does not depend on the presence of amino acids or salts. Latent prints with excellent detail have been developed in the laboratory on various paper products, cardboard and kraft papers.
