Muffle furnace : A muffle furnace or muffle oven (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 heating elementsand widespread electrification in developed countries, new muffle furnaces quickly moved to electric designs

Use of Muffle Furnace:

Muffle furnace is an oven type instrument which can reach high temperatures. The furnace achieves the high-temperature on the basis of the insulating material which is fitted inside the chamber. The insulating material which is provided in the chambers acts as a muffle and stops the heat from escaping out of the chamber. Muffle furnaces are used for the applications where there is huge demand of testing the sample at high temperature and to determine the percent of ash content in those materials.  The industries in which the furnaces are used for treating the samples at high-temperature include:

• Plastic Industry
• Molding Industries
• Glass Industry
• Rubber Industry
• Ceramics Industry
• Biomedical Industries
• Paint Industry
• Textile materials
• Metallurgical applications, etc.
