Stoppers
Glass stoppers are precision-made, ground-glass sealing components used to close laboratory glassware such as flasks, bottles, and reagent containers. Designed to form airtight, chemical-resistant seals, they prevent contamination, evaporation, and spillage during storage or experiments. Their tapered fit ensures compatibility with standardized joint sizes.
Specifications
- Material: Made from borosilicate glass for high chemical resistance and thermal stability.
- Joint Type: Ground-glass taper fit (e.g., 14/23, 19/26, 24/29) for airtight sealing.
- Applications: Ideal for sealing volumetric flasks, reagent bottles, and other lab containers.
- Design: Smooth, precision-ground surface ensures leak-proof closure without additional sealing aids.
