DURAN 217412407 Wide Neck Beaded Rim 100 mL

DURAN 217412407 Round Bottom Flask Wide Neck Beaded Rim 100 mL

The DURAN 217412407 is a 100 mL wide-neck round-bottom flask, manufactured from DURAN® borosilicate glass 3.3, renowned for its excellent chemical resistance, low thermal expansion, and durability. The wide-neck opening (~35 mm OD) allows easy addition of reagents, pouring, and cleaning, making it more practical than narrow-neck equivalents. The round-bottom design ensures uniform heat distribution, making this flask suitable for boiling, reflux, and other heating applications.

Reinforced with a beaded rim, the neck is mechanically stronger and resistant to chipping during handling and cleaning. With uniform wall thickness, the flask provides thermal stability and minimizes hot spots under heating. It complies with DIN ISO 24450 standards for wide-neck round-bottom flasks and is fully autoclavable (~121 °C) for safe sterilization and repeated use. Supplied in packs of 10 units, it is convenient for research, teaching, and industrial laboratories.
