A muffle furnace (sometimes retort furnace in historical usage) is a furnace in which the subject material is isolated from the fuel and all of the products of combustion, including gases and flying ash.[1] After the development of high-temperature electric heating elements and widespread electrification in developed countries, new muffle furnaces quickly moved to electric designs.
Today, a muffle furnace is usually a front-loading box or tube design used for high-temperature applications such as melting glass, creating enamel coatings, technical ceramics or soldering and brazing. They are also used in many research facilities to determine what proportion of a sample is non-combustible and non-volatile (i.e. ash).
Features of Muffle Furnace
Different inner chamber materials with different temperature. Temperature range from 1000°C - 1800°C. Muffle Furnace is High purity alumina fiber insulation and Morgan materials brick PID automatic control via SCR (Silicon Controlled Rectifier) power control with phase angle fired current limiting resistor. 16 programmable segments for precise control of heating rate.
