Round Bottom Three-Angled-Neck Borosilicate Glass Distillation Flask

This 100mL round-bottom distilling flask is made from heavy-duty borosilicate 3.3 glass and features three angled necks with interchangeable ground joints. The center neck socket is 19/26 and both side sockets are 14/23. No stoppers are included. The flask stands 4" tall with a base diameter of 2.5" and a total width of 4.3". The round-bottom design distributes heat evenly during distillation, and the three-neck configuration allows simultaneous connection of a condenser, thermometer, and addition funnel or other apparatus. Borosilicate 3.3 glass is autoclavable and offers superior chemical durability with low thermal expansion. Heat tolerances for this glass are: strain point 515°C, annealing point 565°C, and softening point 820°C.
