The reaction flask is usually made of thick glass and can tolerate large pressure differences, used for air-free chemistry applications or as a means of releasing vacuum and flask from system. Great for blanketing products with inert gas or sealing while under vacuum. 

* Multi - Neck Design: Equipped with two necks ,enabling the simultaneous connection of multiple laboratory apparatus like condensers, thermometers, or feeding funnels, which facilitates complex distillation setups. 

* High - Quality Glass Material: Made from premium lab glass, it boasts excellent chemical resistance, allowing it to withstand the corrosion of various chemical reagents commonly used in distillation processes. It also has good thermal stability, capable of enduring the temperature changes during distillation. 

* Smooth surface:The flask body is smooth,uniform wall thickness distribution suited to heat 

* Customizable: They can also be customized as per one’s requirement.
