Three-Neck Round-Bottom Flask with Bottom Outlet & PTFE Stopcock, 250 to 5000 ml

This three-neck round-bottom flask is designed for versatile chemical processing, particularly where simultaneous distillation, reflux, and material addition are required. Made from Borosilicate glass 3.3, it offers high thermal and chemical resistance, making it suitable for demanding lab applications.

A key feature of this flask is its bottom outlet, fitted with a PTFE stopcock, allowing for easy and controlled drainage or transfer of liquids??especially useful in continuous reactions or multi-step syntheses. The three standard necks accommodate condensers, thermometers, or addition funnels, offering great flexibility for setup.

Whether used for organic synthesis, distillation, or preparative chemistry, this flask provides superior performance, durability, and chemical compatibility.
