Sirchie Dual Purpose Hi-Fi Latent Print Powder, White, 16 Oz. (473 ml)

The Sirchie Dual Purpose Hi-Fi Powder (White) is an oxide powder and it contains a fluorescent substance that permits developed latent prints to be viewed under ultraviolet light. Viewing and photographing latent prints on multi-colored backgrounds are no longer a problem since a bright fluorescence is produced. Excellent contrast under normal lighting is also available on dark surfaces.
