Hollow or solid glass stoppers close glassware items including flasks, funnels, and cylinders to shut out environmental elements for uncontaminated reaction testing. Simple to grease for heating or vacuum procedures, the slightly tapered ground glass joints are easy to rotate for a band without streaks or bubbles. Easily grip penny and hex head design tops for a clean removal upon operating completion. The tightly sealing apparatus closures come in any size needed for a leak-proof seal.
