Lifting Dust Prints

SIRCHIE¨ Finger Print Laboratories, Inc. has refined the art of lifting dust print impressions with the new ESP900 Electrostatic Dust Print Lifter. The Print Lifter consists of a high voltage power supply/control unit, a nickel-plated steel ground plane and a metalized lifting medium. As high voltage is applied to the lifting mat, it takes on a negative charge and the ground plane becomes positive. Any dust present under the mat will take on a positive charge and will then be attracted to the negatively charged collection mat. The dust print that is transferred to the lifting mat will appear as a precise mirror image of the original print. The ESP900 will even lift prints from rough-surfaced floor tile, carpet and even cloth and leather upholstered furniture. The device is compact, lightweight and requires only one pickup mat. The ESP900 operates without wires and with a low current, 10,000-volt static charge.
