Lab Muffle Furnace
The working principle of a lab muffle furnace is to heat the air inside its chamber using the fundamentals of thermal convection and thermal radiation. This is achieved by utilizing heating properties of Nichrome (nickel-chromium) wires which are generally referred to as electrically operated heating elements. The temperature regulation in a furnace majorly depends on the efficiency of electronic controller unit, although best results can only be obtained by applying PID controlled units, PID stands for proportional integral derivative controller. The laboratory muffle furnaces generally do not have sophisticated cooling system. Most of the time a simple fan based exhaust system is installed and cooling is performed by this simple fan system supported by a chimney. The main utility of this furnace exhaust system is to take out the toxic gases from the inner chamber which comes out during heating of the testing materiel / specimen inside the chamber. Hence the chamber gets sanitised of any toxic gases which may have evolved during the heating of materiel inside the lab muffle furnace.

Lab Muffle Furnace fabricated with 304 grade Stainless steel outer body using digital temperature controller cum indicator for impeccable temperature control. These laboratory muffle furnaces are designed to heat the specimens up to 1200°C. Generally the most common laboratory furnaces have a maximum working temperature 1100°C – 1200°C. Applications of a laboratory furnace are a key factor to evaluate the working temperature range requirement. The most vital characteristic to be considered when choosing a laboratory furnace is its maximum working temperature which needs to be in accordance to the application. Insulation is also an important factor to be taken care of for the efficient working of the lab muffle furnace. It is relative and proportional to the working temperature of the furnace, the higher the maximum temperature - heavier the insulation thickness must be. Outer body of the furnace has a thick epoxy coating paint to give it an immaculate and aesthetically desirable appeal and also to enhance the shelf life of the equipment on being operated at elevated temperatures.
The simplest understanding of the use of lab muffle furnace can be explained as its use to burn off desired organic compounds so as to evaluate the amount of inorganic compounds inside a test materiel.
Laboratory furnaces are referred by various names being relative to the application such as bench type furnaces, chamber furnace, ashing furnaces, muffle furnace and dental furnaces too. Laboratory furnaces are generally used to heat small materials or test specimens over 1000°C. Below mentioned is the list of applications of laboratory muffle furnace :
• Research and development.
• Heat Treatment.
• Brazing and Soldering.
• Air and Space Industry.
• Petro chemistry.
• Material Testing and Quality Control Laboratories.
• Coal and Mining.
