Development Chemicals

DFO is a ninhydrin analogue which also responds to amino with better results than ninhydrin processing alone. A laser or forensic light source will cause the latent prints developed with DFO to show fluorescence.

Fluorescamine is a ninhydrin substitute that reacts with the amino acids in fingerprint residues and produces a fluorescent product that renders the latent print pattern visible.

One of the newest and most successful ninhydrin analogs to be recently developed. An extremely sensitive amino acid reported to develop 46% more latents than DFO. Developed prints may be enhanced with Zinc Chloride/HFE-7100 spray and visualized under green ALS light 530nm with dark orange or red filtration. Supplied as pre-measured liquids which are combined before use.

The Iodine Fuming Kit contains a traditional glass tube, Iodine fuming applicators, drying crystals, fiter wool, Iodine crystals, and instructions in a plastic carry case. Our fuming apparatus features a unique one way check valve designed to prevent accidental inhalation of Iodine vapors. > More

Iodine Fuming is one of the traditional development methods which is generally used on porous materials such as paper and cardboard and is generally applied before ninhydrin or silver nitrate processing. Iodine is available in pre-measured vials for use with conventional iodine fuming apparatus. Iodine is for use in a plastic bag fuming chamber or in disposable Iodine Fuming Applicators. The Disposable Fuming Applicator consists of a flexible plastic applicator containing a breakable glass vial of premeasured iodine crystals, drying reagents, and easy flow through filters. The applicator is easy and convenient to use in the laboratory or at scenes. First, attach the mouthpiece tubing to the end of the applicator after removing the plastic cap. Next crush the breakable iodine containing tube by squeezing the center section with your fingers and then open the hinge cap on the front of the applicator. Blow gently through the mouthpiece while holding your palm around the center section to warm and release the iodine vapors which are directed to the surface to be processed. After activation, the applicator can be sealed for reuse by closing the hinged lid on the front of the applicator. > More

The “MBD” fluorescent stain mixture is used with an alternate light source after the cyanoacrylate development of latent prints. It is particularly useful on plastic bags.

The “MRM” fluorescent stain mixture is used with an alternate light source after the cyanoacrylate development of latent prints.

Nile Red stain reagent reacts to the fats and oils (lipids) present in the sebaceous components of latent prints. Nile Red Lipid Stain can be applied by spraying or brushing and can be fluoresced with an alternate light source. Available in premix solution.

The classic method for developing latent prints on paper and other porous objects. We offer the traditional methanol and acetone based formulations as well as a Heptane PE based formulation designed to minimize the running of inks and the HFE-7100 non flammable mix. Also available our new HFE-7100/HFE71IPA formulation designed to be used on thermal and carbonless papers. > More

Oil Red O is a lipid stain which is used for enhancing latent prints produced by the lipids commonly found in fingerprints, foodstuffs, oils, cosmetics, and other fatty substances. Oil Red O has been found to be particularly useful in revealing latents on porous surfaces that have been wet. Compared with physical developer, the ORO technique is much less complex and gives results of impressive clarity and intensity.
