The 2 neck round bottom flask is made of high-quality borosilicate glass, can be heated directly in an open flame and can withstand typical laboratory thermal variations in Chemistry processes like heating and cooling, durable and reusable.
The 2 neck round bottom flask is widely used in the organic chemistry process like distillation, reflux, extraction, reaction etc.
In a distillation apparatus, the 2 neck round bottom flask used as the distillation flask, the straight neck attaches a 3 way distillation adapter or a distillation column(in fractional distillation), the other neck can be used to connect a thermometer adapter, bleeding tube, or additional funnel.
