It is used a laboratory container and mixing jar
No, a beaker is a poor choice of instrument to measure volume. Instead try a graduated cylinder. Generally, the smaller the diameter of graduated cylinder, the more accurate it will be. A grad cylinder will have the increments written up along the side with carefully placed "hash marks" indicating the volume of substance/solution in the cylinder. A breaker may have a few markings indicating the volume of the contents up the side, but not enough make it an accurate measuring device for varying volumes of liquid.
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 burnerfor controlled temperature a water or glycol bathimmersion heatersmicrowave heaterselectric coils under the beaker
Technically any scientist can use a beaker, a beaker is just a measuring tool for liquid. But generally, Chemists are the scientists that use breakers for most of their experiments involving a liquid.
