DURAN 217416803 Wide Neck Beaded Reinforced 3000 mL

DURAN 217416803 Wide Neck Beaded Reinforced Rim 3000 mL

The DURAN 217416803 is a 3,000 mL round-bottom flask manufactured from DURAN® borosilicate glass 3.3, offering excellent chemical resistance, low thermal expansion, and long-lasting durability. Designed with a wide-neck opening and a beaded & reinforced rim, this flask ensures easier filling, pouring, and cleaning while providing enhanced mechanical strength at the neck to resist chipping and breakage.

Its round-bottom geometry and uniform wall thickness enable efficient and even heating, minimizing hot spots when used with heating mantles, baths, or other laboratory heat sources. Supplied as an individual unit (1 flask per pack), this model is part of the non-DIN EN ISO size series, optimized for larger volume handling in laboratory environments.
