Sirchie Crystal Violet Dye

Crystal violet is a dye that will transfer visible color to the fatty components of sebaceous sweat residue in latent prints, producing a highly concentrated, intense, purple image. It is very effective in the development of latent prints on items having a glutinous or sticky adhesive quality, including tape and protective films with adhesive coatings. Crystal Violet is also effective on grease- and oil-contaminated surfaces. Instructions are included.
