For collection of DNA evidence, the Cap-Shure™ protects the cotton tip and sample by using a clear plastic aerated cap. With the cap mounted on the swab, it’s easy to open and close for DNA collection. The sterile swab is centered in the middle of the air drying cap and can be transported to the lab contaminate free without the use of a box.
