Electric Muffle Furnace

New Tech Furnaces Private Limited offers a wide range of electric muffle furnace that is precision engineered to give solutions to laboratories and industrial applications. These muffle furnaces find usage in engineering tests of soils & aggregates, cement testing, ashing organic and inorganic samples, gravimetric analysis and ignition tests. To meet the diverse requirements of our clients, they offer these heaters in various ranges at most competitive prices. 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. 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-type oven or kiln for high-temperature applications such as fusingglass, creating enamel coatings, ceramics and soldering and brazing articles. They are also used in many research facilities, for example by chemists in order to determine what proportion of a sample is non-combustible and non-volatile (i.e., ash). Some digital controllers allow RS232 interface and permit the operator to program up to 126 segments, such as ramping, soaking, sintering, and more. Also, advances in materials for heating elements, such as molybdenum disilicide offered in certain models by Vecstar, can now produce working temperatures up to 1800 degrees Celsius, which facilitate more sophisticated metallurgical applications. The term muffle furnace may also be used to describe another oven constructed on many of the same principles as the box type kiln mentioned above, but takes the form of a long, wide, and thin hollow tube used in roll to roll manufacturing processes.
