Crystal Violet Powder, 25gm
This chemical is ideal for developing latent prints on the sticky side of tape. Each vial contains a pre-measured amount of crystal violet concentrate which will give you a working solution when added to one liter of water. Also available as a ready-to-use pre-mixed liquid. These items are not eligible for return.$30.45 Add to cart -
Gentian Violet 25 gm.
Gentian Violet is extremely useful for developing latent prints that are on the sticky side of any kind of tape. Simply soak the suspected tape in the solution then rinse with water. Latent prints will turn an intense purple color.$37.24 Add to cart -
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.$62.85 Add to cart -
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.$43.05 Add to cart

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.

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.Select options- 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

Ninhydrin
This pre-mixed Ninhydrin reacts with the amino acids in latent print residues to form a purplish blue stain. Commonly used to process paper items. Won't cause inks to run or bleed. Use a common steam iron to accelerate results. Available in an 8 oz spray bottle or a 1 gallon jar.Select options -

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.$43.22 Add to cart
