High quality Suba-Seal™ septa turn-over closure with serrated stopper, ideal for air and moisture-sensitive chemistry procedures. Fits neck ID 19mm. For use with 19/22 joints. After piercing with non-coring needle, the puncture site heals to provide an air- and moisture-tight seal. The closure has a turn-over flange which promotes a double seal in conjunction with annular serrations on the hollow plug. The serrations depress themselves against the inside wall of the bottle neck, making each serration a suction sealing point.
