Puritan DNA-Contamination Tests Lowest in the Industry

If you're looking for sampling swabs, you've come to the right place. Forensic professionals rely on Puritan swabs for clean and accurate sampling. Now you can feel even more confident! Our collection of DNA-free and DNase/RNase-free sampling swabs have been tested by an independent lab. We purposely had this test done to the most stringent standards (less than 25 pg of human DNA). The result? Certified to be DNA-free at a threshold lower than any other swabs on the market today.
