The muffle furnace is a universal heating device. Its resistor wire hidden in the box, the wall of the box is thick, and there is an insulation material, the temperature can rise to 1200℃. It is often used in alkali melting of some insoluble metals and minerals, as well as in gravimetric analysis, flameless ashing of filter paper, burning to decompose organic matter, and driving away volatile components in inorganic matter.

What is the classification of muffle furnace?

For the classification of muffle furnaces, they can be classified according to their heating elements, rated temperatures, and controllers. For details, see the following:

1) According to the heating elements, there are: electric furnace wire muffle furnace, silicon carbide rod muffle furnace, silicon molybdenum rod muffle furnace;

2) According to the rated temperature, it is generally divided into: muffle furnace below 1000°C, 1000℃、1200℃ muffle furnace, 1300°C、1400°C muffle furnace, 1600°C、1700°C muffle furnace and 1800°C muffle furnace.

3) According to the controller, there are the following types: pointer table, ordinary digital display table, PID adjustment control table, program control table;

4) According to the insulation material, there are two types: ordinary refractory brick and ceramic fiber.

  • Furnace body and intelligent controller are separated design, which are beautiful and generous, and the furnace door adopts side-opening design.
  • Adopt heating elements with lining plates on both sides, which is easy to replace the furnace wire. Adopt imported high-temperature heating element, which is more excellent and greatly increases the service life.
  • The use of ceramic fiber insulation greatly improves the heating speed and reduces the heat energy consumption. The heating is fast: the 1000℃ furnace is heated from 100℃ to 1000℃ in less than 30 minutes, and the 1700℃ furnace is heated from 100℃ to 1700℃ in less than 90 minutes. Compared with the traditional muffle furnace, the weight is reduced by 1/2, the heating speed is doubled. The weight is light: the 6-liter furnace weighs only 50 kg, and the 9-liter furnace weighs only 65kg (total weight), which greatly saves energy and increases the service life by 3.5 times; The heat preservation effect is good, the surface temperature of the furnace is low, the temperature is raised to 1000℃, and the surface of the shell is not hot after 1 hour to avoid burns. (About 45-55℃ depends on the use environment)
  • Imported temperature control instrument, brand new digital display, digital set temperature, intelligent control output, which can reduce visual reading and human operation errors, and greatly improve work efficiency.
  • Equipped with a variety of protection devices to improve reliability
  • Independent control system is convenient for maintenance and replacement
  • There are exhaust holes on the furnace body (gas protection inlet and exhaust holes can be added according to user requirements). High efficiency: When used as an experimental furnace, it can open air inlets and outlets, and add a chimney, which is good for replenishing fresh oxygen and speeding up the test.
  • Other specifications can be customized according to user needs: various non-standard tube furnaces, pit furnaces, box furnaces; Various specifications of special-shaped heating devices and heating furnaces can be customized according to user needs!
