Florence Flat Bottom Borosilicate Glass Boiling Flask with Beaded Rim

This 5000 ml Florence boiling flask is made from Borosilicate 3.3 glass and features a flat bottom, narrow neck, and beaded rim. The flat-bottom design allows the flask to sit on a flat surface without additional support, while also being suitable for use with heating mantles and sand baths. The large capacity makes this flask suitable for bulk heating, distillation, and other applications requiring a high-volume flask. The borosilicate glass construction is autoclavable with superior chemical durability. Heat tolerances are: Strain Point 515°C, Annealing Point 565°C, and Softening Point 820°C.
