Description
A Muffle Furnace (muffle hearth) or a Muffle oven is a heating chamber (furnace) in that the sample substance is separated from the fuel as well as all of the produces of combustion, along with gases and flying ash. Subsequently the development of high temperature heating technology along with massive electrification of the developed countries, muffle furnaces quickly moved to electric option.
In electrically heated Muffle Furnaces the resultant byproducts of heating are imperceptible for most processes. An electric Muffle Furnace heats by convection, conduction, or blackbody radiation processes. None of the heating processes create byproducts (combustion by-products) & now such design allows much greater control of temperature uniformity and assure isolation of the heated materials from combustion adulterates.

Important Notes :
- Cracks may appear on the refractory ceramics surface of the chamber. It is normal and can be repaired with alumina coating.
- This Muffle Furnace is not vacuum sealed, testing of toxic, hazardous, explosive gasses or /and substances should not be done without necessary safety arrangements.
- To give long life to the furnace, 10°C /min max heating rate is recomnded. Cooling rate also not to cross 10°C /min.
