Description
This solid glass plug stopper is manufactured from high-quality borosilicate glass 3.3, offering excellent chemical resistance, thermal shock resistance, and optical clarity. Unlike hollow stoppers, this solid plug design provides added weight and durability for a secure fit in standard taper outer joints. The precision-ground conical joint ensures a tight, leak-free seal in 14/20, 19/22, 24/40, and 29/42 outer joints. Ideal for sealing flasks, columns, condensers, and other laboratory glassware during storage, reactions, and transport.
