Flat-bottomed flask: A flask with similar uses as the round-bottom flask, but with a flat bottom that allows it to stand on a level surface. Florence flask: A flask similar to the flat-bottomed flask that has round bodies and either a round bottom or a flat bottom so that one can stand the flask on a level surface. Florence flasks typically ...
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 ...
A pear-shaped Schlenk flask. The flask's sidearm contains a greased stopcock valve, and the flask is capped with a Suba•Seal septum that has not been turned down. The standard Schlenk flask is a round bottom, pear-shaped, or tubular flask with a ground glass joint and a side arm.
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. These types of flask are alternatively called Florence flasks. Flasks with flat ...
