Black SPR Liquid 500 ML Pump Bottle

These Small Particle Reagent (SPR) Spray are pre-mixed in non-aerosol bottles with pump sprayers, and is ready for use directly out of the box. For optimal results, spray using straight, horizontal lines, back and forth above the suspected area so a “wash” of liquid flows over the surface. Use Black SPR on light-colored surfaces and White SPR on dark-colored surfaces and be sure to take a photo of the resulting latent prints. It may be possible to lift the latent prints once dry, although you should photograph them first. Both colors have a fluorescent component that allows fingerprints to be detected using an ultraviolet or forensic light source.
