This engineered fluid is a carrier solvent for Ninhydrin or DFO in latent fingerprint development on porous surfaces. Get more detailed images without CFCs or flammable solvents. HFE-7100 does not dissolve most inks or the amino acids transferred to the porous substrate in a fingerprint. It carries dissolved Ninhydrin or DFO to the edges of fingerprint ridges. And because HFE-7100 does not absorb moisture, ridge diffusion is minimized. > More

Rhodamine 6G is one of the best dyes to use with cyanoacrylate developed latents and a laser or forensic light source. Available as a premix liquid for immediate use, or as a premeasured concentrate to be mixed with one liter of solvent. > More

A methanol soluble fluorescent dye used to enhance cyanoacrylate developed prints. Visualized most effectively at a wavelength of 515nm. > More

Small particle reagent is a well-known technique used to develop fingerprints on wet, oily, or textured surfaces. Our mixture is far superior to others on the market because its formulation mixes better with the water and results in a cleaner application. This technique is almost as easy as using a spray bottle. Simply mix the contents of the vial in a spray bottle with 6 ounces of water. Shake the mixture and spray a gentle mist over the area you are processing. After you see the prints developing, rinse the area with plain water to clean away the excess. Photograph, and when dry, lift by conventional methods. > More

TEC is one of the newer and more successful fluorescent dyes for cyanoacrylate developed latent prints. TEC absorbs uv light near 350nm and emits a narrow band at 614nm. This very wide Stokes Shift contributes to the ease of filtering the excitation light from the fluorescing print which makes it clearer and easier to photograph. The formulation locks the dye into the cyanoacrylate and therefore more dye remains in the print after rinsing. This dye has also been successfully used with cyanoacrylate to develop prints on cadavers. > More
