SPR
Fingerprint Spray
Detects fingerprints on non-porous (even moist) surfaces,
light or dark. Simply spray the suspect
surface with SPR.
See
an immediate result that can be lifted when dry. No risk to you or the environment.
SPR Spray
is the long awaited solution for detecting fingerprints
on wet, light and dark, non-porous surfaces.
This is a truly unique product. The old-fashioned
method of fingerprint detection, based on
dispersed particles in an aqueous solution, required
mixing the powder, water and other ingredients
in the field and applying propellants and
other tools. This process was messy, cumbersome
and the whole point of simplifying and expediting
the work of the Scene of crime officer was
missed.
Furthermore, the powder would simply create a
thick mud-like liquid and would stick to everything.
In cases where fingerprints had to be found
quickly, and in several locations, this method
was impractical.
SPR Fingerprint Spray is a valuable investigation tool that helps preserve
and collect important evidence at the scene of
the crime. In most cases it can be used by less
trained personnel, saving valuable time of laboratory
techniques. Easy to carry, simple and safe to use.

Technical Data and Background (.pdf format)
Application:
Just shake the can, spray evenly on a vertical surface
where fingerprints are sought. The fingerprints
appear in seconds. After drying, the fingerprints
can be lifted and preserved as usual.
Directions to use:
1) Shake well before use. Spray away from body
on to surface from a distance of 20-30 cm until
the whole surface is wet. Spray a continuous stripe
over the area that was previously sprayed.
DO NOT USE ON HORIZONTAL SURFACES:
The fluid flushes the surface and coats it with the
spray (black or white).
2) Let the excess liquid drip. Image
development may take longer with SPR white.
3) Wait until the area is completely dry.
4) Lift the prints as usual or photograph the prints
before lifting.
SPR
Black is an aerosol-based fingerprinting product for the
development of latent prints on wet, light, smooth non-porous
surfaces. Earlier methods based on dispersed particles in aqeuous
solutions required the field mixing of powders, water and other
ingredients to achieve similar results. The process was messy
and cumbersome. Furthermore, the powder often created an ineffective
mud-like liquid. SPR Black or White overcomes past problems
by incorporating product modifications, which result in a prepackaged
solution
that is warranted with a shelf life of 1 year. As an investigative
tool, it helps preserve and collect important evidence
at the scene of the crime.
