Investigation-Forensic Field Test Kits IFT-100E

   Our family of forensic and investigation products provide law enforcement officers and investigators distinct advantages for field and laboratory use. They insure a testing process, which is convenient, fast, sensitive and inexpensive.


See-Through is a transparency spray that officials can use to inspect the contents of closed envelopes or paper wrapped packages without opening or damaging them, and without leaving any marks.

   It is ideal for inspecting suspect envelopes and packages for potential security risks (specifically substances suspected of being drugs, bio-agents and/or explosives). Foreign matter, such as a powder, will be seen as a darkened area in the envelope.

   See-Through is a clear, non-conductive liquid that when sprayed on a suspect envelope or document will allow the user to clearly see the contents. After the document or envelope is dry (it dries in minutes), See-Through will not leave any traces or watermarks. Nor does it cause inks to run.

   See-Through is available in 300ml, 200ml and 100ml sizes.

UV Trap

UV Trap is an oil-based, ultraviolet invisible identification spray designed to mark non-porous items (e.g. door handles, desks, etc.) for investigative purposes. UV Trap offers several distinct improvements over conventional ultraviolet marking products. First, UV Trap is an oil-based spray, not a dry particulate in either powder or pencil form. Consequently, it is not easily transferred to others. Second, because the ultraviolet particles are embedded inside the oil, when a marked item is touched, the ultraviolet particles are safely deposited on top of skin cells making it almost impossible to wash off. The ultraviolet particles will remain on the skin for a minimum of 48 hours despite repeated washing with soap and water.

SPR Black




   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 aqueous 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 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, SPR Black helps preserve and collect important evidence at the scene of the crime.

Nin Plus Ultra

   Nin Plus Ultra is an aerosol-based latent fingerprint development product for use on porous surfaces (e.g. checks, paper, etc.). Nin Plus Ultra dramatically shortens print development time. Latent fingerprints begin developing in as few as 20 minutes with no other tools required. With the application of a wet heat source, development can be accelerated to within 5 minutes. Nin Plus Ultra does not damage the surface and does not cause inks to run.

   Nin Plus Ultra contains active ninhydrin. Other processes of ninhydrin tub testing involves harmful chemicals and compounds that effect the ozone layer such as Freon and CFC's. NIN PLUS ULTRA, however, provides the same results without harming the environment. It meets candle tests for non-flammability.


   Allprint is the pre-packed solution for the detection and visualization of fingerprints on light, non-porous, dry or wet, even oily surfaces (e.g. wax papers, candles). Simply spray with Allprint, flush with water, fingerprints appear dark against the light surface. Allprint is a ready to use, fine-calibrated reagent, packed in a spray can, to achieve the best results.

Crystal Violet

Our Crystal Violet product is an aerosol spray used for the visualization of fingerprints on surfaces that have been treated with cyanoacrylates. Crystal Violet is also an excellent stain for visualizing fingerprints on the sticky side of an adhesive tape. Elkat's easy-to-use aerosol version of the essential Crystal Violet chemical means that there is no messy, time-consuming preparation or mixing of powder/concentrate with water. Just spray, flush with water, and see the results. Once the fingerprints are stained with the Crystal Violet spray, the results can be easily seen and photographed.


Blue is a unique tool for the development of footprints. Spraying directly on a non-porous surface will reveal the pattern of any undisturbed footprint that exists. The pattern will appear blue on a yellow background. It can be used on wooden, stone and linoleum floors and similar surfaces, which makes it an easy tool for footprint visualization, when casting is not an option.


Ferrotrace is an iron image detection spray that reveals invisible iron traces left on a suspect's hands after touching a weapon. Ferrotrace offers superior sensitivity, convenience and ease of use over other currently available field tests. Even after a weapon (e.g. gun, knife, hand grenade, etc.) has been removed from the crime scene (or destroyed), an officer can quickly screen a large number of suspects by spraying Ferrotrace directly onto hands, palms, fingers or environmental surfaces such as paper. If the suspect was in contact with the weapon containing iron elements, the invisible iron traces will turn a dark violet color. Positive reactions appear only from touching iron which is uncoated. Ferrotrace is non-toxic. Back
