Heating Mantles

  • As long as the layers of fiberglass cloth remain intact, the heating mantle will pose no shock hazard.
  • Always use with a variable autotransformer to control the input voltage.
  • Do not exceed the input voltage recommended by the mantle manufacturer. Higher voltages will cause it to overheat, melt the fiberglass insulation and expose the bare heating element.
  • Heating mantles should not be used for vacuum distillation of heat sensitive or unstable materials. It's difficult to regulate precise temperature control.
  • Never operate heating mantle without fluid within the flask.
