Muffle Furnace

Muffle Furnace


The muffle furnace is an extremely hot chamber, the walls of which can heat the irradiated material, which is kept inside so that there is no direct contact of the material. These furnaces are often used in testing laboratories as a means of creating extremely high temperatures inside the chamber. They are employed to measure the characteristics of materials at high and required temperatures. These devices are used to measure the characteristics of materials at extremely precise and high temperatures. These furnaces are also known as smashing furnaces. It is more oven type appliances that can easily achieve very high temperatures i.e. up to 900oC or 1200oC. It is capable of producing high temperatures because it is equipped with a high-temperature heating coil in insulated material of glass wool. This material acts as a muffle and prevents heat from escaping.


Muffle furnace is used for many applications such as:

  • Fusing Glass
  • Making enamel coatings
  • soil
  • soldering
  • Brazing
  • Rubber and Polymers

In addition to these well-known applications for ash content determination, muffle furnaces are also used in many research centers, medical laboratories, to determine the non-volatile and non-combustible proportions of samples. The test equipment is also used for highly sophisticated metallurgical applications. All types of muffle furnaces operate with conventions, conduction based, and electrical resistance heating elements.

Presto Stentest provides high quality of muffle furnaces to create high temperatures inside laboratories to determine the actual percentage of ash content in a material.
