About this item
Suba-Seal® Septum Stoppers are made from natural red rubber.
They are flanged stoppers with a hollow plug and sleeve extension that folds down over the neck of the vessel. They have a series of annular serrations on the plug portion of the septa. Each of these serrations depress along the inner wall of the glass vessel to form an extremely effective air-tight seal.
