Latent Print Development using Cyanoacrylate Ester
Method |
|
This
series of Hard Evidence™ cyanoacrylate (super-glue)
fuming products were first introduced in the mid -1980s
and since that time have assisted investigators around
the world in the development of latent prints on
nonporous surfaces such as plastics, metal, glass, and
both finished and unfinished wood.
Cyanoacrylate fumes react with the residue in latent
prints and produces a white visible print which can be
processed with powder and photographed. |

Hard Evidence™ Fuming Pouches |
|
|
|
 These
fingerprint developing pouches are an easy to use one-part
fuming system. Each peel-open pouch contains cyanoacrylate
in a gel form which will not spill, leak or flow from the
opened pouch.
To use Hard Evidence™ Fuming Pouches, simply place the item
to be fumed for prints in a fuming chamber, fish aquarium,
or large clear plastic bag along with a small container of
warm water to increase humidity. Peel open a fuming pouch
and place the pouch in with the item. Fuming and print
development starts immediately and usually takes 20-30
minutes to thoroughly develop prints. |

Liquid Hard Evidence™ Latent Print Developer |
|
|
|
|
Liquid Hard Evidence™ Latent
Print Developer works essentially the same way the pouch
design does, however, in order to accelerate the generation
of cyanoacrylate fumes, a hot plate is frequently used.
Simply pour the appropriate amount of liquid Hard Evidence™
into a small aluminum tray and place the tray on an electric
hot plate. |
