Bi-Chromatic Fingerprint Powder

Lightning Powder® Bi-Chromatic™ fingerprint powder has the remarkable properties of appearing black when dusted on a light-colored surface and silver when dusted on dark-colored surfaces. Using a Zephyr® Fiberglass Brush and Bi-Chromatic™ Powder, you can dust up to 90 percent of the surfaces found at most crime scenes. The greatest advantage of using Bi-Chromatic™ Powder is that the lifted prints will be black when placed on a white backing card. This eliminates the bother of comparing latent prints with light-colored ridges on a black background against rolled prints with black ridges on a white background. It also means that only white backing cards will be needed. Products purchased online are for domestic sale and domestic use only. These items are controlled for export from the US.
