The DURAN 217315406 is a 1,000 mL flat-bottom flask with a wide neck and beaded rim, made of DURAN® borosilicate glass 3.3. Designed for general heating, liquid handling, and distillation applications, its flat base ensures the flask stands on flat surfaces without needing a support ring. The wide neck enhances access for pouring, filling solids or liquids, and eases cleaning. Uniform wall thickness allows better heat distribution and reduces thermal stress during heating. Sold in packs of 10 units.
