Forensic Source Black Magnetic Fingerprint Powder Similar in tone to Forensic Source's standard black latent print powder, Black Magnetic Powder is recommended for use in dusting glossy papers (such as magazine covers), tissue paper, rough or polished wood, leather, plastics, glass, and rubber.
• Works exceptionally well on plastic baggies after they have been treated with cyanoacrylate esters (superglue fumes)
Forensic Source White Magnetic Fingerprint Powder Suggested for use on dark surfaces where white contrast is desired. Latent prints dusted with white powder must be placed on black backing cards for the highest contrast when photographing.• Provides excellent white contrast for dark surfaces
Forensic Source Silver/Grey Magnetic Fingerprint Powder Many technicians prefer Silver/Gray powder due to its high sensitivity for developing latent prints on so many different surfaces. Silver/Gray is an ideal powder for use on all glass, metallic, hard rubber and highly-varnished surfaces.
• Extremely adhesive powder which will adhere to many surfaces that a standard latent print powder will not
Forensic Source Bi-Chromactic Magnetic Fingerprint Powder Bi-Chromatic™ powder has the unique quality of appearing black when dusted on light-colored surfaces and silver when dusted on dark-colored surfaces.• Lifted prints are always black, so only white backing cards are needed.
Noted for its coal-black hue and property of adhering to the latent print, but not to the background surface, Lightning ® Black Powder has been used by latent print examiners and crime scene technicians for over 70 years.
It is a heavy powder which will not float around in the air and "dust" the technician as well as the print. Lightning® Black Powder is recommended for most general dusting situations with either a Zephyr® Fiberglass Brush or a camelhair brush.
Latent Print Powder Features:
• Heavy powder will not float around in the air
Forensic Source Lightning® 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.
Forensic Source Bi-Chromactic Fingerprint Powder Features:
• Powder appears black when dusted on a light-colored surface and silver when dusted on dark-colored surfaces
