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.
An oil bath air filter at the upper left in a GAZ-21 engine 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 This type of air filter was used in car and tractor engines, but has been replaced by modern paper air filters; some small engines continue to use this system.
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
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
Unless there is a big mess, like hair clippings or hair dye, cleaning the bathroom sink once a week along with the rest of the room should keep bacteria away and the sink looking fresh.
A metal block might be used instead of an oil bath. Some modern instruments have automatic optical detection. The measurement can also be made continuously with an operating process. For instance, oil refineries measure the freeze point of diesel fuel "online", meaning that the sample is taken from the process and measured automatically.
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.
