The electric burners combine the advantages of a regular gas burner with the simple operation of a heating mantle. While the heating element guides the radiant heat to the top cavity, the top cowl keeps the extreme temperatures safely away from users. Electric burners can be used for heating test tubes, crucibles, small flasks, and beakers. Air circulation holes allow the unit to be held by the base or placed on a bench top while operating.
