Here is a surface residue identification product that offers major advantages in narcotics investigation cases. Packaged in individual foil envelopes, the 1" x 11/2" swabs are easy to carry in a pocket. When wiped across a surface on which there is good reason to suspect the presence of cocaine, these NIK Substance ID Swabs turn color. Test results are immediate. These swabs are sensitive to trace amounts of residue, far less than could be collected for regular field testing. When test results show a positive result, this may be sufficient cause for further investigation. Unlimited shelf life assures these swabs will provide accurate, reliable results, when and where you need them.
