Industrial 1000 mL Round Bottom 3-Neck Boiling Flask Angled Joints Boiling Flask

The 1000 mL Round Bottom 3-Neck Boiling Flask with Angled Joints is a borosilicate glass laboratory vessel designed for heating, distillation, reflux, and multi-component reactions. It has a 1000 mL (1 L) capacity with three necks—one center neck and two angled side necks—featuring standard taper ground glass joints (commonly 24/40) for attaching condensers, thermometers, stirrers, or addition funnels. Constructed to ASTM E438 Type I, Class A, the flask uses borosilicate glass and offers temperature resistance up to 500°C (932°F) with excellent chemical resistance to acids, solvents, and alkalis; it is compatible with heating mantles, oil baths, sand baths, or heating blocks. Applications span organic chemistry, pharmaceutical research, chemical synthesis, and educational laboratories where controlled heating and multi-point access are required; the product is listed as new with surplus inventory available.
