Rubber Cork Stopper, Extra Soft, Solid
Low Durometer Rating: Engineered with a significantly lower Shore A hardness than standard laboratory closures, allowing the material to deform easily for a hermetic seal against irregular glass surfaces.
High-Recovery Vulcanization: Manufactured through a specialized process that ensures the stopper maintains its pliable, "extra soft" compression properties even after repeated exposure to chemical reagents and sterilization cycles.
