China No. 3023 Fiberglass Latent Print Brush

No.3023 Fiberglass latent print brush

1. Purpose:

Dip copper or aluminium metallic powders to sweep and uncover latent fingerprint. Suitable for sweeping and uncovering large areas of latent fingerprints.

2. Features:

Made of superfine fiberglass. The fiber is fine, which makes it easy to be penetrated by powders. As a result, the fiber retains more powders and one dip of the powders may be useful for multiple times of latent fingerprint-sweeping.

3. Method:

a) For powders with ceramic balls: insert the fiberglass brush into the powder container, rotate the handle to make the fiberglass brush sweep over the ceramic balls and stick the powders, which then can be directly used to sweep and uncover latent fingerprints.

b) For ordinary powders: dip copper metallic powders or aluminium metallic powders with the fiberglass brush, put the brush hair in the powder container cap, rotate the brush handle so that powders can evenly permeate to the brush. Rotate the brush handle to shake off the excess powder.

c) Develop latent fingerprint: sweep the fingerprint along the ridge line until the fingerprint appears.
