Round-bottom flask

Round-bottom flasks (round-bottomed flasks or RB flasks) are types of flasks having spherical bottoms used as laboratory glassware.

They are used mostly for chemical or biochemical work.^[1] Today, they are usually made of heat-resistant borosilicate glass. There is at least one tubular section known as the neck with an opening at the tip. Two or three-necked flasks are made. Round bottom flasks come in many sizes.
