Selecting the right fingerprint brush can lead to an identification, selecting the wrong brush can lead to a damaged print. Latent prints can easily be damaged by a brush that is too stiff or is used with excessive force. Conventional brushes are typically made with animal hair, fiberglass filaments, or feathers.

This Cyclone Fiber Brush has been precision milled to spin, twirl, and evenly sweep fingerprint powder over the desired surface. This 6.5” long brush consists of thousands of specially formulated glass fibers to insure softness and maximum coverage without damaging prints. The brush will hold the correct amount of powder and distribute it evenly, resulting in fewer trips to the powder jar. Our Cyclone Brushes are made to last, and will grow better with age. Packaged in a reusable plastic tube which opens on both ends for easy storage and removal. Use one brush for black powder, one for dual use powder, and one for white powder.

TIPS FOR SUCCESS:
Powders applied with a traditional filament brush, like that in the Cyclone, consist of very fine particles and are usually low density or “fluffy” in nature. This enables particles to be easily picked up or “loaded” onto the brush filaments. The low density of this  powder also allows it to easily become airborne during the dusting process, making a dust mask or respirator necessary at the crime scene.It is important to keep brushes clean, dry, and relatively free of tangles. To apply fingerprint powder with a conventional brush, the filament tips are lightly dipped into a sterile, wide-mouth container holding a small amount of powder. This is called “loading” the brush. Excess powder is then shaken, spun, or tapped from the brush. The powder is then applied evenly to all areas of the substrate. An area of the surface (or a substrate similar in nature) should be tested before fully processing the item. This is done to establish the optimum amount of powder to be used on that substrate and to avoid background painting. Brushing is accomplished with light and even strokes that resemble painting. It is always important to begin by lightly powdering and slowly building to heavier applications to minimize fingerprint damage.

Finally, a word of caution may be in order. Although using fingerprint brushes are quick and inexpensive, concerns have been raised recently concerning the possibility of contamination due to the transfer of DNA through the use of fingerprint brushes (van Oorschot et al., 2005, pp 1417–1422). Crime scene examiners are being warned to be aware of this possibility, especially when processing major scenes (The Fingerprint Sourcebook - NCJRS, 211, pp 7.4-7.12).
