Abstract (en)
[origin: EP0391614A2] A laboratory heating mantle comprises an insulating body (1,2,3) defining a hollow heating chamber (6) closed from below by a sheet (5) of ceramic glass. The top wall (3) has an aperture (4) to receive and support a vessel (10). A radiant heating element in the form of a halogen heat bulb (8) (or a printed resistance element, not shown) is mounted below the sheet, which freely transmits heat to the chamber (6) and at the same time protects the element from accidental spillage.
