DURAN 217316402 Flask Wide Neck Beaded 2000 mL

DURAN 217316402 Flat Bottom Flask Wide Neck Beaded Rim 2000 mL

The DURAN 217316402 is a 2,000 mL flat-bottom flask manufactured from premium DURAN® borosilicate glass 3.3, designed for laboratory heating, boiling, distillation, and reagent preparation. The wide-neck opening (~50 mm OD) provides excellent accessibility for adding reagents, pouring, and cleaning, while the beaded rim reinforces the neck for improved durability and resistance to chipping.

Its flat base allows the flask to stand securely on benches or hot plates without the need for additional support rings, enhancing convenience and safety during use. With uniform wall thickness, this flask ensures consistent heating and reduced thermal stress, making it highly reliable for everyday lab applications.

Supplied in packs of 10 units, it is suitable for both research and teaching laboratories requiring robust, easy-to-handle glassware.
