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 air born contamination and/or sample loss so common when vials with internal threads are used. The screw top incorporates a moulded-in sealing ring, which assures a tight leak-proof seal.
