In the laboratory, solutions are often heated. This step can be carried out using different techniques, e.g. in a water or sand bath, with a heating hood or classically using a Bunsen burner. If the Bunsen burner is used as the heat source, it is recommended to use a tripod or square foot and a corresponding glass ceramic plate. The vessel to be heated is placed on the glass ceramic plate with the Bunsen burner underneath. Contamination of the glass ceramic plate can be removed with the cleaning scraper.
