A Florence flask is a type of flask used as an item of laboratory glassware. It is used as a container to hold liquids. A Florence flask has a round body with a flat bottom and a single long neck. It is designed for uniform heating, boiling, distillation and ease of swirling; it is produced in a number of different glass thicknesses to stand different types of use. They are often made of borosilicate glass for heat and chemical resistance. The flask is named after Florence, Italy. Traditional Florence flasks typically do not have a ground glass joint on their rather longer necks, but typically have a slight lip or flange around the tip of the neck. A common volume for a Florence flask is 1 litre.[1]
