Where are muffle furnaces used?

A muffle furnace is a special laboratory furnace that can be used in a wide variety of areas. For example, muffle furnaces are ideal in the following areas:
  • In the laboratory: When it comes to protecting samples or specimens from direct heat radiation or flames, you are very well advised to use a muffle furnace in your laboratory and institute work. Laboratory furnaces of this product category are also used in chemical analysis and in physics, for example in gravimetric processes.
  • In themetal and steel industry: Thermal treatment with a muffle furnace is essential for hardening steel and metal workpieces.
  • In crematoria: The combustion chambers of crematoria are also equipped with muffle furnaces.
  • In distilleries: For the production of porcelain, bricks and other objects made of clay materials, muffle furnaces are very suitable.

Design and function of a laboratory muffle furnace.

In a muffle furnace, the heat source is separated from the rest of the firing chamber by a heat-resistant insert. The protective insert is called a muffle and serves to protect samples and other materials to be heated from direct exposure to flames and heating element radiation as well as from gases. Temperatures of up to 1,400 degrees Celsius can be reached in modern ceramic-lined muffle furnaces. In the MedSolut portfolio, for example, you will find muffle furnaces with the following functions:
  • With ceramic muffle

Muffle furnaces in which the heat protection devices inside are made of ceramic are particularly robust. Very high temperatures can be reached in them, which is not only relevant with regard to selected laboratory samples at work, but also in distilleries or crematoria, among other places.
  • With included scale

To ensure maximum precision when working with heated samples, offers high-quality, high-performance muffle furnaces that are equipped with a built-in scale. This allows the sample to be measured before and after the heating process, among other things, and the specific mass to be determined.
  • With integrated exhaust gas cleaning

When heating substances, exhaust gases are produced which, in conventional furnaces, are extracted separately by means of an exhaust system. The functional muffle furnaces on have an integrated exhaust gas cleaning system, which makes the use of the furnace even more economical and energy-efficient overall.
  • With loss-in-glow determination

Muffle furnaces designed for loss-on-glow applications offer particular advantages when working in the laboratory. You benefit from more efficient and environmentally friendly operation and even more precise results.
  • With afterburner

Muffle furnaces with afterburners are used for the direct removal of toxic or harmful vapours that may be generated during heat treatment processes.

Correct use of a muffle furnace in the laboratory

One of the special features of the muffle furnaces in the MedSolut online catalogue is that each model offers you a wide range of parameter settings. This is fundamental with regard to generating precise results. Depending on the product or sample, the dimensions of the kiln should be conceptualised. This is because uniform temperature control can only be guaranteed with the right size. Check the insulation properties in advance. Also, the bottom of the oven should be covered with solid silicon carbide plates and a mitred shell. This will prevent the impact of heating elements during loading and unloading. The muffle should be heated separately before the tempering process. Especially in moulds that can be heated to a particularly high temperature level. After inserting the sample, make sure to seal the tr absolutely tightly to avoid possible heat loss and to increase the efficiency. In addition, such a procedure has an effect on the economy of the respective application. Regular monitoring of the temperature control process provides an additional measure of safety and helps to achieve optimum results with every procedure.

Selecting the right size

Size is also important if you want to find the perfect muffle furnace for your projects. Certainly, the ideal size depends on the size of the samples or specimens to be heated. But the number of pieces also plays a role. If your oven is always fully loaded, the highest efficiency can be achieved.
  • Smaller muffle furnaces with a capacity of up to 40 litres are ideal for smaller workpieces, samples or test objects.
  • If you need to fire larger quantities of smaller individual workpieces, a medium-sized muffle furnace is a good choice. The heat distribution can be targeted in the inner segment.
  • Large-volume muffle furnaces with a capacity of about 450 to 500 litres are used for heating specific materials and substances in larger quantities. In addition, the use of a large muffle furnace is recommended when it is necessary to fire individual pieces gently, evenly and at a moderate level.
Note: When setting up your muffle furnace, take into account the need to allow for a breathing space. This means that, for safety reasons, there should be a minimum distance of about 50 to 100 cm from the wall or other equipment.
