Round bottom flask with Joint necks is designed for laboratory synthesis, reaction, reflux, distillation and multi-port glassware assemblies.
the three-neck structure provides more connection points for condensers, adapters, addition funnels, thermometers, gas inlet tubes or other compatible laboratory glassware components.
The angled neck layout gives users more side access and wider spacing between connected accessories. This makes the flask practical for reaction setups where several components need to be connected at the same time, especially when a vertical-neck layout feels too tight or difficult to operate.
The round bottom body supports common heating, stirring and reaction workflows in chemistry laboratories and research environments.
