Lighting Powder Black SPR Spray (500ml Pump Bottle)
Small Particle Reagent is used to develop latent print on wet or damp surfaces. It is not necessary to let the surface dry. SPR Spray is pre-mixed in non-aerosol bottles with pump sprayers. There is no mixing of solutions. Spray using straight, horizontal lines, back and forth above the suspected area so a "wash" of liquid flows over the surface. Two colors of SPR Spray are available, black and white. Use the black SPR on light-colored surfaces and the white SPR on the dark-colored surfaces.
A third type of SPR Spray is available for use with a UV lamp. Spray the UV solution on multicolored surfaces and view it under a long wavelength ultraviolet lamp. Photograph the resulting latent prints. It may be possible to lift the latent prints once dried, however, it is necessary to photograph them first.
Shelf life: 6 months from purchase. Keep in a cool, dark place.
