Trace Collection Tape
Many agencies use standard latent print lifting tape for trace evidence collection. Using the widest lift tape you have on hand, press firmly against the surface where trace hairs and fibers are suspected. The hairs, fibers and other trace evidence will adhere to the adhesive side of the tape. You can then place the tape on a clear sheet of acrylic or a plastic bag. However, recovery of the trace evidence from lift tape is somewhat more difficult when compared to a methanol soluble tape.
Methanol Soluble Tape - 3M Trace Collection Tape
3M is famous for Forensic Source's Scotch Brand adhesive tapes, but this soluble tape is one you may not heard about. To collect trace evidence, such as hairs and fibers, repeatedly press a length of the methanol soluble tape over the suspected surface. This could be a car seat, the floorboard of a car, a couch or sheets from a bed, etc.
To recover the trace evidence, place the tape in a beaker of methanol just deep enough to cover the tape. Wait until the methanol has dissolved the adhesive on the tape. Remove the paper tape backing from the beaker. Pour the methanol through a filter and collect the trace evidence remaining on the filter. Each roll is 2 inches in width and 180 feet long.
