Round-bottom flasks are shaped like a tube emerging from the top of a sphere. The flasks are often long necked; sometimes they have the incision on the neck, which precisely defines the volume of flask. They can be used in distillations, or in the heating a product.

For example, a round bottom flask, Liebig condenser, and oil bubbler with ground glass joints may be rapidly fitted together to reflux a reaction mixture. This is a large improvement compared with older methods of custom-made glassware, which was time-consuming and expensive, or the use of less chemical resistant and heat resistant corks or ...
Dropping funnels are usually constructed with a ground glass joint at the bottom, which allows the funnel to fit snugly onto a round bottom flask. This also means it need not be clamped separately. [1] Dropping funnels have been in use since at least the mid-1800s. [2]
