Puritan’s dry transport system securely holds a swab in a round bottom tube made from virgin polypropylene resin, creating a safe and sterile environment to accommodate many different styles of collection devices. The injection molded cap assures a precision fit for multiple handle styles eliminating any foreign adhesive which may interfere with the specimen. Tubes include a distinctive label describing product identity, expiry date as well as allow for patient identification and collection information. The labels also act as a tamper resistant seal when attached to the cap.
