What is a Florence Flask?
In a laboratory setting, a Florence flask, sometimes referred to as a boiling flask, is used by scientists and other professionals who specialize in science. It has a distinct round shape and is comprised of a bulbous body and an elongated neck. Its main aim is to heat a liquid uniformly, whenever that’s required heat distribution would be required. As for its construction, it is primarily pursued to be constructed through borosilicate glass, allowing the instrument to endure high levels of heat. The most common use cases for the instrument tend to be storing liquids, boiling them and mixing together different compounds. The shape adds an added benefit, there are almost zero stress points during the heating process assuring that scientific workflows will never be put at risk.
Introduction to the Instrumental Flask
The flask is available in a variety of sizes, from 50 mL to 2000 mL, ensuring adequate volume for whatever an experiment may require. The design typically constitutes a flat bottom or a rounded corner with flat bottomed flasks being more stable on surfaces while the rounded corner ones are ideal to be used with a support ring or clamp in order to be even heated.
