The vial has external threads, providing a smooth and uniform inner surface, thus reducing the risk of contamination. Tubes can be autoclaved (121°C) in upright position with caps loosened. These leakproof tubes are tested with silicone washer screw caps at 20PSI. Available either plain or with printed graduations and white marking area. Order caps separately.
