In a laboratory there are several methods to heat liquids in beals or other glassware depending on the temperatures you wish to attain and the control you wish to have over the temperature,
- For rapid heating a stand supporting the beaker over a Bunsen burner or Maker burner
- for controlled temperature a water or glycol bath
- immersion heaters
- microwave heaters
- electric coils under the beaker
