Manufactured by Puritan Medical Products Co., the DNA collection swab consists of a highly porous, shred-resistant, medical grade foam tip on a polypropylene stick. The sponge-tipped swab yields more DNA than cotton swabs for dilutions, including those from post-luminol treated bloodstains. The Puritan swab is produced in a FDA GMPs and ISO 9002 certified facility to ensure the product is sterile until use.
