Muffle Furnaces

These economical, benchtop muffle furnaces have one-piece ceramic chambers with the heating elements completely hidden. They are suitable for most heat-treatment processes at temperatures up to 1050°C (1922°F) or higher for brief periods. For particular applications, these furnaces may also be equipped for adjustable airflow or controlled inert atmospheres, special controller requirements, over-temperature protection, remote monitoring etc.

These silicon carbide muffle chamber furnaces provide the ideal furnace conditions for gold cupellation work and many other processes where indirect heating and controlled airflow are required. The heat energy is provided by coiled wire elements, as in the wire embedded type furnaces, but located in an outer chamber. The excellent thermal conductivity of silicon carbide provides a working chamber with almost no temperature variations. Controlled airflow passing through the chamber is pre-heated allowing full use of the available hearth area.
