Circulating water baths (also called stirrers [10]) are ideal for applications when temperature uniformity and consistency are critical, such as enzymatic and serologic experiments. Water is thoroughly circulated throughout the bath resulting in a more uniform temperature.
This glossary of chemistry terms is a list of terms and definitions relevant to chemistry, including chemical laws, diagrams and formulae, laboratory tools, glassware, and equipment. Chemistry is a physical science concerned with the composition, structure, and properties of matter , as well as the changes it undergoes during chemical reactions ...
A pot of oil on a heat source. 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 equilibrium fraction of decomposed molecules increases with the temperature. Since thermal decomposition is a kinetic process, the observed temperature of its beginning in most instances will be a function of the experimental conditions and sensitivity of the experimental setup.

Fractional distillation in a laboratory makes use of common laboratory glassware and apparatuses, typically including a Bunsen burner, a round-bottomed flask and a condenser, as well as the single-purpose fractionating column. Fractional distillation. As an example, consider the distillation of a mixture of water and ethanol. Ethanol boils at ...
Heated bath schema. 1: Heated substance. 2: Heating medium. 3: Laboratory flask. 4: Bowl. 5: Gas burner. 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 ...
Diagram of a vacuum flask Gustav Robert Paalen, Double Walled Vessel. Patent 27 June 1908, published 13 July 1909. The vacuum flask was designed and invented by Scottish scientist James Dewar in 1892 as a result of his research in the field of cryogenics and is sometimes called a Dewar flask in his honour.
