The 3-neck round bottom flasks are made of high quality borosilicate glass, uniform wall thickness, durable and reusable.
The three necks distilling flask designed with a round bottom and vertical necks which allows to attach three lab glassware components for distillation apparatus.
Round bottom design having spherical bottoms are more resistant to fracturing under vacuum, as a sphere more evenly distributes stress across its surface and allows more uniform heating or boiling of a liquid.
Round bottom flasks are often used to contain chemical reactions for reflux set-ups and laboratory-scale synthesis.
It also can be used as a distilling flasks and receiving flasks for the distillate.
