DURAN 217112404 Narrow Neck Beaded 100 mL

DURAN 217112404 Flat Bottom Flask 100 mL Narrow-Neck Beaded Rim

The DURAN 217112404 is a 100 mL flat-bottom flask crafted from DURAN® borosilicate glass 3.3, offering excellent resistance to thermal shock and chemical corrosion. Its flat base provides stability on laboratory benches and hot plates without requiring a support ring, making it highly practical for heating and reaction work.

The narrow-neck design allows controlled pouring and reduces spillage, while the beaded rim reinforces the neck opening for greater mechanical strength and resistance to chipping. With uniform wall thickness, this flask ensures reliable heating performance and long-term durability in repeated laboratory use.
