The Yash Instruments Hollow Stopper with Flat Bottom is a premium laboratory essential designed for sealing volumetric flasks, mixing cylinders, and reagent bottles. Unlike traditional round-headed stoppers, our flat-bottom design ensures that when the stopper is removed, it can be placed securely on the laboratory bench without the ground surface touching the table.
Crafted from high-quality low-expansion borosilicate glass, these stoppers offer excellent resistance to chemical attack and thermal shock. The precision-frosted ground joint provides an airtight seal, preventing the evaporation of volatile chemicals and ensuring the integrity of your samples.
