Erlenmeyer Flask vs. Florence Flask: What's the Difference?

Edited by Aimie Carlson || By Janet White || Published on December 23, 2023
Erlenmeyer flask is a conical, flat-bottomed lab flask. Florence flask is a round-bottomed, bulbous lab flask.

Key Differences

The Erlenmeyer flask, named after Emil Erlenmeyer, is a conical, flat-bottomed flask used in laboratories. In contrast, the Florence flask, also known as a boiling flask, has a round bottom and is often used for boiling liquids.
Erlenmeyer flasks are ideal for mixing and heating chemicals, as their sloped sides prevent spillage. Florence flasks, with their spherical bottoms, distribute heat more evenly, making them suitable for uniform heating of liquids.
The wide base of the Erlenmeyer flask provides stability, reducing the risk of tipping over. The Florence flask, due to its round bottom, requires a stand or support for stability during use.
Erlenmeyer flasks are commonly used for titration experiments, as they allow easy swirling of contents. Florence flasks are frequently used in distillation setups due to their ability to handle prolonged heating.
In terms of measuring volume, Erlenmeyer flasks often have graduations for approximate measurements. Florence flasks are not typically used for measurements and lack volume markings.
