Manufactured from premium clear borosilicate glass, these heavy-duty stoppers are designed as direct replacements for lost or broken volumetric flask closures. Because they are constructed entirely from glass, they offer absolute chemical resistance and will not degrade, crack, or contaminate your sample like rubber or silicone alternatives.\u003c\/p\u003e\n\n\u003cp class=\"my-2 [\u0026amp;+p]:mt-4 [\u0026amp;_strong:has(+br)]:inline-block [\u0026amp;_strong:has(+br)]:pb-2\"\u003eEach stopper features a precision-ground joint that creates a flawless friction fit with standard taper glassware, effectively preventing the evaporation of volatile solvents and protecting sensitive solutions from atmospheric contamination. The 3080 Series features a classic flat-head pennyhead design, allowing the stopper to be placed upside down on the laboratory bench to prevent the ground joint from picking up benchtop contaminants.
