Forensic Chemicals | FOR CYANOACRYLATE SEE: Glue Fuming Supplies |
Knowing the correct chemical process for latent print development is essential. Although research is constant and new techniques and processes are being developed almost daily, sometimes the most basic processes are still the best for your individual needs. MSDS sheets for use of these chemicals will be furnished with your order upon request. Note: Evident, Inc. does not assume responsibility for the health risks associated with the use or misuse of these products. Caution should be taken with these chemicals as certain health risks do exist. |

Iodine The use of iodine fumes to enhance latents prints on porous surfaces is one of the most tried and true processes available. Evident now has 5 different forms of iodine application available. Traditional Iodine Crystals are ready to use in glass ampoules at an extra low prices. The Iodine Fuming Applicators are the standard blow-through design which provide concentrated and directed fuming. The Iodine Fuming Kit contains a traditional glass fuming apparatus, drying crystals, glass wool, and iodine crystals in a field case. The Iodine Print Enhancement Applicators are designed for use after iodine fuming to add additional detail. |

Physical Developer Components Physical developer is a silver-based aqueous reagent that reacts with the components of sebaceous sweat in latent prints to form a silver-gray deposit. It can be used to develop latent prints on paper and some other porous materials. Mix the solutions and immerse documents in the mixture. |

|
Silver Nitrate Silver Nitrate is typically used on pourous materials after Ninhydrin processing to produce a dark brown color. Silver Nitrate reacts to the chlorides present in latent prints, and requires exposure to sumlight or ultraviolet light in order to develop. Evident provides either a 8 ounce premixed methanolic solution spray or as a crystalline form in premeasured vials. Crystals are sold in a package of six 2.2 gm vials. |

DFO - 1,8-Diazafluoren-9-one DFO is used to develop latent prints on porous surfaces. DFO reacts to the amino acids present in perspiration. The resulting prints will fluoresce with the use of various lasers and light sources. DFO can be either dipped or sprayed. After processing with DFO, the item must be dried and placed in an oven at approximately 100º Celcius (212ºF) for twenty minutes. An iron (no steam) may be used if an oven is unavailable. Available in 3M™ Novec™ HFE-7100 mixture, which provides greater operator and environmental safety. |

Rhodamine 6G One of the most brilliant dye stains for latent print development on non-porous items with lasers and alternate light sources, after processing with cyanoacrylate. Evident offers Rhodamine 6G as a premixed 1 liter liquid, or in powder form to be mixed with solvent. |
|||||||||||
|
 |
Crystal Violet This stain is commonly used for developing latent prints on the adhesive side of virtually all types of tape. A simple solution of crystal violet and water will produce impressive results. |
|||||||||||
|
|
Ardrox Fluorescent Dye Spray This fluorescent spray is designed for enhancing latent prints that have been developed with cyanoacrylate. It provides excellent ridge details when the latent print is saturated with Ardrox. Prints fluoresce yellow/green. Comes in a 1 liter spray bottle for easy application. Use ultraviolet equipment for viewing results. |
||||||||
|
MBD Mixture MBD Mixture is used after cyanoacrylate processing. MBD is fluorescent when exposed to an alternate light source. MBD is offered as a premixed liter. |
|||
|
Sudan Black Sudan Black is one of the best methods for developing fingerprints on greasy or waxy non-porous surfaces such as glass, metal, milk cartons, interiors of gloves, and candles. The resulting print development is a dark blue-black. 1 liter ready to use. |
|||
|
Thenoyl Europium Chelate (TEC) A fluorescent dye used to enhance cyanoacrylate developed latent prints on non-porous surfaces. Visualized most effectively with long-wave UV only. Submerge or flood the item for 2 minutes, then let dry. Expose to long-wave for maximum development. |
||||||
|
 |
Basic Yellow 40 This dye is designed to enhance latent fingerprints developed with cyanoacrylate on non-fluorescent, multi-colored surfaces. Prints fluoresce bright yellow/green between 365nm and 485nm with an alternate light source or a UV light. EVIDENT offers Basic Yellow 40 as a premixed liter of liquid. |
||
|
Basic Red 28 Basic Red 28 is a red dye for use on cyanoacrylate developed prints. After staining with Basic Red 28, a light source or or UV light is used to visualize the prints. Evident offers Basic Red 28 as either a premixed liquid for immediate use, or as a premeasured concentrate to mix with 1 liter of Petroleum Ether or Methanol. |
|||
|
Red-Yellow Mixture This mixture of both Basic Red 28 and Basic Yellow 40 provides the user with a wide range of fluorescence with cyanoacrylate developed prints. Red-Yellow Mixture is offered as a premixed 1 liter liquid. |
|||
|
RAY Mixture This mixture of Basic Red 28, Ardrox, and Basic Yellow 40 provides a wide range of fluorescence with cyanoacrylate developed prints. Offered as a premixed liter of liquid. |
|||
|
RAM Mixture RAM is a fluorescent stain mixture of Rhodamine 6G, Ardrox, and MBD. Use RAM with an alternate light source after processing with cyanoacrylate. Particularly useful in the enhancement of CA developed prints on plastic bags. After processing with cyanoacrylate, RAM may be applied by spraying, dipping, or flooding. Follow with examination under a light source, UV lamp, or laser. Sold as a premixed liter. |
|||
|
Acid Fuchsin Acid Fuchsin is an excellent stain for enhancing bloody fingerprints or footwear impressions, and has the unique characteristic of fluorescence when viewed under a light source or laser. Bloody latent prints and footwear impressions can be lifted with a white gelatin lifter, then photographed as is or viewed and photographed under your light source, excited at 515-560nm, and using a red barrier filter (600nm). |
||||||
|
Fluorescein This chemical mixture of Fluorescein causes a catalytic reaction to occur between the hemoglobin in blood, and oxygen. This reaction produces a luminescent stain which will luminesce in the dark when excited with UV or ALS. The major advantage of Fluorescein is that it will continue to luminesce for hours under UV or ALS after the initial application, and without additional applications of the reagent. This product is commonly used to detect blood spatter, blood stained fingerprints and footwear impressions, as well as, blood evidence which has been concealed or cleaned. Fluorescein also reacts with materials other than blood, and therefore caution should be exercised when interpreting luminescent areas. |
|||
|
Zinc Chloride Zinc Chloride is a traditional method of enhancing prints on porous materials after processing with Ninhydrin. Offered as a 1 liter solution in Methanol. |
|||
|
Nile Red Nile Red is a lipid stain which reacts to the fats and oils present in a latent print. Nile Red fluoresces with an alternate light source. Apply by spray or brushing onto surface. Available as a premixed liquid, Methanolic or Aqueous. |
|||
|
Phloxine B Phloxine B is a protein stain which develops a reddish-orange colored print. Phloxine B is particularly good when used to develop latents on dark-colored or multicolored backgrounds. Evident offers Phloxine B as a premixed 1 liter liquid. |
|||
|
Amido Black Develop faint and often invisible bloody fingerprints and foot impressions with this protein dye stain. Incredible results on most surfaces, even human skin. |
|||||||||
|
LCV - Leuco-Crystal Violet An effective protein stain used to develop and enhance bloody fingerprints or footprints deposited on non-porous surfaces. Various protein stains, such as amido black, etc., can be used after processing with LCV. Cyanoacrylate fuming may be detrimental to this process. Spraying is the most effective method of application. Use a fine mist, development will occur within 30 seconds. Contains fixative. |
