SIBATA Standard Taper Glass Stoppers meet ASTM E-675 Specifications. These stoppers are lightweight yet very strong to reduce chipping and breakage, thus minimizing replacement costs. The flat top design allows the stopper to stand on its head, which frees the user’s hand and minimizes potential contamination. Fully interchangeable with other common flask stoppers and fit all standard labware of comparable ST size.
