Gellifters have been specially developed to lift fingerprints, shoe prints, dust marks, and micro traces. The thick, non-aggressive, low-adhesive gelatin layer makes it possible to lift traces from almost every surface, including porous materials such as paper or cardboard. Lifted prints can be taken along for photography or closer examination.
The black Gellifters have a carrier of linen rubber and are protected by a transparent polyester film. Black Gellifters can easily be marked, since the white linen rubber backing can be written on. Lifted prints or marks can easily be photographed after removing the cover sheet. When the prints have been photographed, the cover sheet can be replaced (after carefully cleaning it to remove any possible contamination). Gellifters are normally stored at room temperature (20° Centigrade, 68° Fahrenheit), though storage in a refrigerator is not harmful. The Black Gellifters have no known shelf life. Due to the presence of (food-grade) preservatives in the gelatin layer, fungal growth on the Gellifters will not occur.
