A heated bath is used in the laboratory to allow a chemical reaction to occur at an elevated temperature. (2025). 9780582462366, Pearson/Prentice Hall. ISBN 9780582462366
In contrast to traditional Bunsen burner, heated baths use liquids to transfer heat to the reaction vessel. This is achieved using a high-boiling point liquid inside a thermally conducting bath (usually made of metal). Water and silicone oil are the most commonly used fluids. A water bath is used for temperatures up to 100 °C. An oil bath is employed for temperatures above 100 °C.
The heated bath is heated on an electric hot plate, or with a Bunsen burner. The reaction vessel (Florence flask, Erlenmeyer flask, or beaker) is immersed in the heated bath. A thermometer is usually kept in the fluid to monitor the temperature.
