Ninhydrin Aerosol Spray, 6 oz.

This is an aerosol formulation of Ninhydrin. Simply spray NIN-Print on the evidence you wish to process and allow it to air dry in a fume hood or under controlled conditions. Latent prints may take a few days to fully develop, but prints may begin to appear after a few hours. All Ninhydrin solutions should be used with proper respiratory protection or in a fume hood. NIN-Print is flammable and requires an additional surcharge to ship by air.
