Cryo-Lok™ vials are ideal for storage or transport of material at extremely low temperatures. The vials have external threads, providing a smooth and uniform inner surface. This eliminates the problem of airborne contamination and/or sample loss so common when vials with internal threads are used. The screw cap incorporates a molded-in sealing ring which assures a tight, leakproof seal.
