Helios Heating Mantle

A heating mantle is a piece of equipment used to apply heat to containers, as an alternative to other forms of heated baths. In contrast to other heating devices, such as hotplates or Bunsen burners, glassware containers may be placed in direct contact with the heating mantle without substantially increasing the risk of the glassware shattering, because the heating element of a heating mantle is insulated from the container so as to prevent excessive temperature gradients.
