Another use of an oil bath is to filter particulates out of air, by leading the air stream through an unheated oil bath. This type of air filter was used in car and tractor engines, but has been replaced by modern paper air filters; some small engines continue to use this system. In some cases oil baths are used to heat bearings so they expand ...
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 over up to and 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 ...
Different types of water baths are used depending on application. For all water baths, it can be used up to 99.9 °C. [2] [3] When the required temperature is above 100 °C, alternative methods such as oil bath, silicone oil bath or sand bath may be used. [4]
Silicone oils are primarily used as lubricants, thermic fluid oils or hydraulic fluids. They are excellent electrical insulators [ 2 ] and, unlike their carbon analogues, are non- flammable . Their temperature stability and good heat-transfer characteristics make them widely used in laboratories for heating baths ("oil baths") placed on top of ...
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. A bain-marie is also used to melt ingredients for ...

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.
