Our quick drying Ninhydrin Spray is supplied in an easy-to-use pump misting bottle and is an extremely sensitive method for developing old latent prints on paper documents, letters, newspaper, envelopes, wrapping paper, checks, and even wallpaper at a crime scene.
Ninhydrin reacts to the proteins and amino acids found in fingerprints. When ninhydrin is sprayed on the suspected area, the print will appear purple in color when heated to approximately 220 degrees in an oven or with a hair dryer or infrared lamp.

Fingerprints developed Ninhydrin will fade and should be photographed. Additionally, you can use fixative to preserve the latent prints developed.
