DURAN 217417602Wide Neck Beaded Reinforced 6000 mL

DURAN 217417602 Round Bottom Flask Wide Neck Beaded Reinforced Rim 6000 mL

The DURAN 217417602 is a 6,000 mL round-bottom flask made from DURAN® borosilicate glass 3.3, providing exceptional chemical resistance, low thermal expansion, and durability for demanding laboratory workflows. Its wide-neck design (≈ 89 mm OD) simplifies filling, pouring, and cleaning, while the beaded & reinforced rim strengthens the neck opening to resist chipping and mechanical stress.

Thanks to its round-bottom geometry and uniform wall thickness, the flask ensures even heat distribution, minimizing hot spots during heating. This makes it highly suitable for large-scale boiling, distillation, reflux, and solution preparation. Classified as a non-DIN EN ISO size, it is supplied individually (1 flask per pack) for specialized lab needs.
