FAQ
Frequently Asked Questions
Essentially, yes. 'Florence flask' is a specific, traditional name for a round-bottomed boiling flask. In modern labs, 'round-bottom flask' is the more common generic term.
The etymology is uncertain but is traditionally said to originate from the city of Florence, Italy, possibly where this style of glassware was originally produced or became widely used for chemical purposes.
No, its spherical, round bottom means it cannot stand upright on a flat surface. It must be held in a clamp, placed in a heating mantle, or set on a specialised ring stand or support.
Its primary uses are for boiling liquids, distillation setups, and chemical reactions where even heating of the contents is required, often involving a heat source like a Bunsen burner or heating mantle.
