The EPA vials are ideal for water sample collection for volatile organic analysis. The vials with unbonded septa have a molded-in retainer ring to keep septa firmly in place while allowing septa to be removed and replaced as needed. Also there are vials with the septum permanently bonded to the cap for secure sealing.
