Crime Scenes and Alternate Light Sources- where can i buy biological washing powder fluorescent powder fingerprint ,Apr 04, 2013·When using fluorescent chemicals, latent fingerprint development can be greatly improved. Fluorescent latent print powders have the ability to make the latent residue on a surface fluoresce. The benefit here is that the ridges fluoresce brightly and when photographed, a multi-colored or confused background can be minimized to the point where it ...BVDA - Fingerprint PowdersPowders develop fingerprints by preferential adhesion of fine particles to the deposited ridge details. The adhesion of the particles is influenced by the presence of aqueous and/or fatty components in sweat, or by sticky contaminants in the print. There are many types of powder and several methods of application.
Alternate Light Sources are typically used in crime scene investigation to identify many forms of evidence. Physiological fluids (semen, urine, and saliva) can be identified through their natural fluorescent properties utilizing UV light.

One Lumicyano kit LK5-100 (including a 5 gm Lumicyano Powder bottle) allows: 37 cycles in a 650 liter (23 cub.ft) fuming chamber
New fluorescent fingerprint tag aims to increase IDs from 'hidden' fingerprints on bullets and knives. A new way of detecting and visualizing fingerprints from crime scenes using colour-changing fluorescent films could lead to higher confidence identifications from latent (hidden) fingerprints on knives, guns, bullet casings and other metal surfaces.
