An oil bath is a type of heated bath used in a laboratory, most commonly used to heat up chemical reactions. It is a container of oil that is heated by a hot plate or (in rare cases) a Bunsen burner .
The oil level is a little low now to compensate for expansion when heating commences. The Thiele tube, named after the German chemist Johannes Thiele, is a laboratory glassware designed to contain and heat an oil bath. Such a setup is commonly used in the determination of the melting point or boiling point of a substance.
A laboratory bath could refer to any of the following: Cooling bath: a laboratory device that lowers the temperature of the bath or improves heat conduction; Heated bath: a laboratory device that raises the temperature of the bath to enhance a chemical reaction; Laboratory water bath: a laboratory device that maintains the temperature of the bath
A heated bath is used in the laboratory to allow a chemical reaction to occur at an elevated temperature. [1] In contrast to traditional Bunsen burners, 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).
In the laboratory, this solution is sometimes used to clean glassware, though it is discouraged in many institutions and it should not be used routinely due to its dangers. [10] Unlike chromic acid solutions, piranha does not contaminate glassware with Cr 3+ ions. Piranha solution is particularly useful when cleaning sintered (or "fritted ...
A bain-marie on a stovetop. A bain-marie (English: / ˌ b æ n m ə ˈ r iː / BAN-mə-REE, French: [bɛ̃ maʁi]), also known as a water bath or double boiler, a type of heated bath, is a piece of equipment used in science, industry, and cooking to heat materials gently or to keep materials warm over a period of time.

The diagram shows a typical reflux apparatus. It includes a water bath to indirectly heat the mixture. As many solvents used are flammable, direct heating with a Bunsen burner is not generally suitable, and alternatives such as a water bath, oil bath, sand bath, electric hot plate or heating mantle are employed.
