Fingerprint Powder

Fingerprint powder is a type of powder used in forensic investigations to enhance and visualize fingerprints left at a crime scene. It is classified under the supply class Miscellaneous Chemical Specialties in the supply group Chemicals And Chemical Products.

Fingerprint powder is typically composed of finely ground particles that adhere to the oils and sweat present in fingerprints, making them visible to the naked eye or under certain lighting conditions. The powder is applied to the surface where the fingerprints are suspected to be present, such as on glass, metal, or other smooth surfaces.

There are different types of fingerprint powders available, including black, white, gray, and fluorescent powders. The choice of powder depends on the surface color and the desired contrast for better visibility.

Black fingerprint powder is commonly used on light-colored surfaces, while white or gray powders are used on dark-colored surfaces. Fluorescent powders are used when the fingerprints need to be visualized under ultraviolet (UV) light.

Fingerprint powder is an essential tool in forensic investigations as it helps investigators identify and collect evidence from crime scenes. It is important to handle and store fingerprint powder properly to prevent contamination and preserve its effectiveness.
