Muffle Furnace

Home / Our Products / Furnaces / Muffle Furnace

A Muffle Furnace is a high-temperature, laboratory or industrial furnace used for heat treatment, material testing, and sample analysis. It features a sealed, insulated chamber (muffle) that isolates the material from direct contact with heating elements, ensuring uniform heating and preventing contamination.

Types of Muffle Furnaces

Laboratory Muffle Furnace
- Small-scale furnace for chemical analysis, ashing, and testing.
- Used in research labs, pharmaceuticals, and universities.
Industrial Muffle Furnace
- Larger, high-capacity furnace for metal heat treatment and ceramics.
- Common in manufacturing, metal processing, and aerospace industries.
Electric Muffle Furnace
- Uses electric resistance heating elements (silicon carbide or kanthal wires).
- Ensures precise temperature control with minimal pollution.
High-Temperature Muffle Furnace
- Can reach ultra-high temperatures (up to 1800^oC).
- Used for ceramic sintering, glass melting, and advanced material testing.
Programmable Muffle Furnace
- Equipped with PLC/SCADA systems for automated temperature control and ramp-up cycles.
- Ideal for complex heat treatment and research applications.

Key Features of Muffle Furnaces
