Silicone oil bath
Piston (3) in the silicone oil bath (4) with a Bunsen burner (5). Silicone oil (2) is used as the heat transfer fluid. The liquid to be heated (1) is in the round bottom flask (3) on which a reflux condenser (NOT shown here) is usually placed.
The silicone oil bath , also known as silicone oil bath , consists of a container filled with warm or hot silicone oil , in which there is another container with the substance to be heated. Silicone oil baths can be used universally and are used during the heating of substances in chemical laboratories for heating to 250 ° C . Below about 95 ° C , water baths are usually used because of the high heat capacity of the water and the resulting inertia, which favors precise automatic thermostatting.
Use in laboratories
As far as possible, no water should get into silicone oil baths, since otherwise the bath liquid will foam and splash unpleasantly when heated.
