The Puritan HydraFlock Cap-Shure Swabs provide a standard 7” plastic shaft sterile cotton collection swab enclosed with a breathable plastic capsule.  Puritan 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.  This design holds the specimen near the outside of the fibers for easy release during analysis.  The resealable capsule provides secure protection for the collected sample.  The plastic shaft of this swab will break evenly prior to packaging.  Securely package in the Large Swab Box and paper evidence envelope.  Provided in packages of 50, 100, or 500 swabs.
