These DNA-Free Flocked Swabs feature special fibers which increase the amount of sample collected and allow for the easy release and recovery of that sample during analytical processing. The small fibers are bonded perpendicularly to the swab shaft. This design holds the specimen near the outside of the fibers for easy release during analysis. The PurFlock Ultra DNA-Free Swabs feature higher absorbancy for increased collection capability. Provided in packages of 50 or 500 sterile swabs. Available as DNA-Free tested swabs.
