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 This type of air filter was used in car and tractor engines, but has been replaced by modern paper air filters; some small engines continue to use this system.
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.

In further contrast to other methods of applying heat to a flask, such as an oil bath or water bath, using a heating mantle generates no liquid residue to drip off the flask. Also, heating mantles generally distribute heat evenly over the surface of the flask and exhibit less tendency to generate harmful hotspots.
The bath is a fundamental product in any laboratory. Over the years, water baths have evolved from basic analog tools to advanced digital machines capable of sophisticated and programmable controls, functions, and capabilities. Key features in water baths often include: Multi-language operation; User-settable limit values
