DURAN 217417302 Wide Neck Beaded Reinforced 5000 mL

DURAN 217417302 Round-Bottom Flask, Wide Neck, Beaded & Reinforced Rim, 5000 mL

The DURAN 217417302 is a 5,000 mL round-bottom flask made from DURAN® borosilicate glass 3.3, engineered for high durability, chemical resistance, and thermal stability. Its wide-neck design with a beaded & reinforced rim provides easier access for filling, pouring, and cleaning while offering enhanced protection against chipping and mechanical stress at the neck opening.

The round-bottom geometry with uniform wall thickness ensures even heat distribution, making the flask ideal for boiling, reflux, distillation, or other heating processes. Its large 5 L capacity makes it particularly suitable for scale-up experiments, industrial research, and teaching labs. Classified as a non-DIN EN ISO size, it is supplied as a single unit (1 per pack).

Features

• Large Capacity (5000 mL) – Suitable for bulk solution handling and large-scale experiments.
