TECHNICAL INFORMATION

Electrostatic Dust Print Lifter

Catalog No. ESP900

Information

One of the most overlooked forms of physical evidence at the crime scene is impression evidence. Locating

and recovering obvious kinds of impression evidence like tire tracks and

footprints is not the problem. It’s the not-so-obvious dust print impres-

sions that are difficult to locate, accidentally damaged or obliterated. The

Electrostatic Dust Print Lifter is designed specifically for lifting these

dust prints from almost any surface from the floor, door, wall or win-

dowsill to upholstered furniture using static electricity. High voltage is

applied to a metallized lifting mat creating a negative charge

and causing the ground plane to become positively charged.

Any dust present under the mat will take on a positive charge,

attracting it to the negatively charged mat.

The resulting dust print lifted will be a pre-

cise mirrored image of the original print.
