Explosive trace detection swabs, the 25-count Calibration Swabs are ideal for those lower throughput screening environments whether as part of the TSA passenger checkpoint process or as a part of a robust cargo screening method.  The material used for Rapiscan Systems' (previously Morpho Detection) calibration traps is a high-quality Teflon® coated fiberglass optimized for use in Rapiscan trace detection equipment. Calibration Swabs have highly tested and optimized quantities of specific standards embedded onto the surface of the trap under strict laboratory and quality controls in order to ensure the proper functionality of Rapiscan trace detection equipment. 

For ease of identification, Calibration Traps are stamped with the letter "C." Calibration Traps are intended for single use only and should be discarded after each use. In order to maximize the longevity of this product, the container should be securely closed immediately after obtaining the required trap.  The Calibration Swabs are housed in a new plastic clam-shell packaging for ease of access.
