Muffle 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 furnace quickly moved to electric designs.
JinYu muffle furnace have many experiments and procedures taken in the lab requiring extreme heat environment. For this purpose, JinYu high temperature muffle furnace steps in as the necessary part of laboratory equipment. JinYu Universe Group are providing the muffle furnace at a affordable cost including vacuum box furnace, crucible furnace, dental furnace, hydrogen furnace, vertical furnace, chamber furnace, and etc. The sizes of the muffle furnace is various from the smaller muffle furnaces which are conveniently placed on a workbench, to the larger units that has a coveted capacity and competent for all duty.

Today, a muffle furnace is a box-type oven or kiln for high-temperature applications such as fusing glass, 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. Some digital controllers allow RS232 interface and permit the operator to program up to 50 segments, such as ramping, soaking, sintering, and more. Also, advances in materials for heating elements, such as molybdenum disilicide MoSi2 heating elements offered in certain models by JinYu, can now produce working temperatures up to 1,800 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.
Both of the above mentioned furnaces are usually heated to desired temperatures by conduction, convection, or blackbody radiation from electrical resistance heating elements. Therefore there is (usually) no combustion involved in the temperature control of the system, which allows for much greater control of temperature uniformity and assures isolation of the material being heated from the byproducts of fuel combustion.
