Chemglass Round Bottom Flask 3 Neck 29/42 CN 24/40 SN Heavy Wall 500mL Jacketed

The Chemglass CG-1538-02 is a 500 mL capacity, heavy-wall, three-neck round bottom flask that is entirely jacketed for precise temperature control during chemical reactions. It is constructed from durable borosilicate glass, offering excellent chemical resistance and thermal stability. The flask features a 29/42 standard taper outer joint on the center neck and two 24/40 standard taper outer joints on the side necks, allowing for the connection of various laboratory apparatus such as condensers, stirrers, thermometers, or addition funnels. The full jacketing of the flask, complete with two hose connections, enables the circulation of a heating or cooling fluid from an external circulator, ensuring uniform temperature distribution throughout the reaction mixture.
