DURAN 217415404 Round Bottom Flask Wide-Neck Beaded Rim 1000 mL

The DURAN 217415404 is a 1,000 mL round-bottom flask featuring a wide-neck opening (≈ 50 mm) and a beaded rim, made from DWK Life Sciences’ DURAN® borosilicate glass 3.3. This flask is part of the wide-neck round-bottom boiling/flask family, designed for better accessibility (filling, pouring, cleaning) due to the wide mouth. The beaded rim provides mechanical strength at the neck, helping reduce chipping and improving durability. Uniform wall thickness ensures more even heating, reducing hot spots when used on heating mantles or other heat sources.
