Muffle Furnace
We are a provider leader of Muffle Furnace Manufacturers in India. We offer these furnaces for laboratory and industrial areas. It is a high-temperature device and it is designed for maintaining heat, material testing, and thermal processing. It operates by isolating the sample from direct contact with the heating elements, ensuring clean and controlled heating up to temperatures of 1200°C or more. The furnace features an insulated chamber where heat is distributed evenly. It is commonly used in chemical labs, metallurgy, ceramics, and R&D centers.

A muffle furnace is an important tool for accurate and contamination-free thermal processes. Choose our muffle furnace and it is available in various sizes and models to suit your specific heating needs.
What is a Muffle Furnace?
A muffle furnace consists of an insulated chamber heated by electric coils. The sample is placed inside a separate chamber (the “muffle”), which protects it from contaminants and ensures uniform heating. These furnaces can reach temperatures up to 1200°C or higher, depending on the model and application.
Muffle Furnace Uses
Ash Content Determination : Used in industries like food, plastics, and rubber to burn off organic materials and calculate ash residue, helping determine purity and composition.
Material Testing : Ideal for thermal analysis of metals, ceramics, and glass, including testing how materials behave under high heat conditions.
Heat Treatment of Metals : Used for annealing, tempering, and hardening metal parts in tool manufacturing, automotive, and aerospace industries.
Chemical Analysis : Supports gravimetric analysis and loss-on-ignition tests in chemical labs to measure changes in weight after heating.
Ceramic and Glass Work : Essential for sintering, fusing, and firing ceramics and glass materials, ensuring strong, finished products.
Paints and Coatings Industry : Used to determine the organic and inorganic content in painted or coated samples by burning off volatile substances.
Pharmaceutical and Clinical Research : Used for sterilization and preparation of samples requiring precise high-temperature conditions.
Muffle Furnace Working Principle
- Electric heating elements (usually made of Kanthal, Nichrome, or Silicon Carbide) are placed around the outer walls of the chamber.
- These elements heat up when electric current passes through them, raising the temperature of the surrounding insulated chamber.
- The heat is transferred to the inner chamber (muffle) via conduction and radiation.
- The sample placed inside the muffle is heated uniformly in a contamination-free environment, as it is isolated from the heating elements and combustion gases.
- A temperature controller (usually digital or PID) helps regulate and maintain the desired temperature for precise heating.
