The perfect tool for collecting biological samples. It's a sterile Dacron polyester tipped wooden shaft 4.5” swab in a tube. Simply remove the black end cap, then twist open and remove the swab, take your sample, and then return the swab to the tube with the opposite end open. Complete the sample collection information on the tube label. The entire tube can then be put into a bag or box, and will dry during transport. No more handling, no tying up drying cabinets or evidence lockers. Reduced risk of cross contamination, greater evidence integrity. Our kit includes two Crime Scene Swabs, one 3 ml vial of sterile water, and two 6” x 9” windowed paper evidence bags and two evidence bag seals, all sealed in a polybag.
