Sie suchten nach: Sandbäder
Since the sand must first be heated, the sand baths gradually increase the flask temperature. Similar to the water variation, the sand conforms to the shape of the vessel but will not evaporate or spill. Completely surrounding the reaction vessel, the conducting particles spread heat evenly. The laboratory equipment is heated with a burner flame or hotplate incorporated. Without imposing a particular temperature limit, the sand baths working range is more extensive.
