  • Amido Black

    Amido Black is useful for enhancing latent prints contaminated with blood, but it will not successfully develop a normal perspiration-based print. Although it will not detect the typical chemical components of latent prints, Amido Black is very sensitive to the proteins found in blood and some other body fluids. It leaves a blue-black stain and is usable on both porous and nonporous surfaces. *(h) - Additional hazardous shipping fee applies, call for details. These items are not eligible for return.

  • Ardrox Forensic Reagent

    Ardrox is a fluorescent liquid dye, which works well with lasers, forensic light sources and UV lamps. While Ardrox-developed prints fluoresce under 365nm, better results have been reported while examining evidence with light in the 450-480nm spectrum.
    • Can be used full-strength or diluted with ethanol or methanol
    • Ardrox has a shelf-life of one year

  • Blood Fixative

    Blood Fixative is highly recommended for setting fingerprints or impressions left in blood. Before using aqueous based developers, the blood should be dry and fixed to prevent disruption or running of the blood during enhancement. These items are not eligible for return.

  • 1,2-Indanedione, 100mL

    An extremely sensitive amino acid reported to develop 46% more latents than DFO. The consistency and quality make this the best in the industry. 99% purity. These items are not eligible for return.

  • Indanedione 1 gram

    Develop latent prints for a fraction of the price of DFO with Indanedione! This one gram bottle will give you the ability to capture numerous fingerprints off of porous surfaces. When used with proper lighting, Indanedione can visualize prints as well, if not better, than other methods like DFO. A recent study showed that Indanedione developed 46% more identifiable fingerprints than DFO on actual exhibits! For proper use and storage, Indanedione should be prepared for use shortly before needed. Storing prepared Indanedione for long periods of time will alter the chemical structure, making it less effective than freshly prepared Indandione. Indanedione is not intended for use on poor-quality papers such as newspaper, cardboard or recycled paper.

  • Leuco Crystal Violet

    Leucocrystal Violet reacts with the heme-group in blood to give a violet color. Its application can be used to identify bloodstains that are not visible and to enhance and provide additional contrast to bloodstain patterns that are visible. This reagent contains hydrogen peroxide, so if used on heavy bloodstains foaming may result and cause loss of detail. Leucocrystal violet is typically used on porous surfaces. These items are not eligible for return.

  • Ninhydrin Forensic Solution

    Ninhydrin is one of the easiest and most effective methods for developing latent prints on paper. Many latent print examiners use Ninhydrin exclusively on paper because of its effectiveness and/or their lack of a proper setup for DFO. Ninhydrin should always be used in fume hood or with an appropriate filter mask.
    • Very economical
    • Can also be mixed with 3M Novec Engineered Fluid HFE-7100 for a less toxic and non-flammable solution
    • Crystals have an indefinite shelf life
    • Working solution is one year

  • p-DMAC Paper

    Preferred method for processing thermal paper and items sensitive to heat. May be used on any porous item needing latent development. May be especially useful on colorful backgrounds since there is high fluorescence when viewed with ALS. Best results usually visualized between 475nm and 515nm with an orange barrier filter or glasses. Shelf life: 6 months. To extend longevity of this protect always store in the provided amber sleeve. EXCELLENT FOR PROCESSING PRINTS ON CURRENCY! These items are not eligible for return.

  • 3M Novec Engineered Fluid

    Developed by 3M scientists as a CFC replacement, Novec is a safe, non-ozone-depleting solvent that is known for producing the crispest ridge detail on porous surfaces. Use as a carrier solvent with Ninhydrin or DFO. Its low surface tension, low viscosity, and high density allows the fluid to more thoroughly and easily care dissolved DFO and Ninhydrin to the edges of the fingerprint. And since it doesn't absorb moisture, the ridge diffusion of the print is maximized. Use on a wide range of inks and substances and experience minimal smearing or running.

  • DFO

    Items treated with DFO often give 2 - 3 times more print development than if treated with Ninhydrin alone. It can be sprayed on or dipped into.
