Adorama Crystal Violet Latent Print Protein Stain Rinse/Destain, 1 Liter Bottle

Crystal Violet is a simple and effective protein stain used to enhance prints on the sticky side of tape and items that are oily or greasy. It is important that any biological evidence such as semen, urine, or blood, as well as any trace evidence have been collected before use. Crystal Violet can be used on duct tape, masking tape, clear plastic tape, surgical tape, black electrical tape, and other tapes. It should not be used on surfaces that contain a water-soluble adhesive. Because Crystal Violet is a protein stain, it can also be used to enhance bloody prints.
