Muffle Furnace

About Muffle Furnace

This is a muffle furnace, and from the image it appears to be a lab-scale electric model with a front-loading chamber.

Main parts visible in the image:

1. Outer Body Metal casing, usually powder-coated, housing the heating chamber.

2. Insulated Heating Chamber The white ceramic/refractory-lined space where samples are placed for heating.

3. Door with Insulation Keeps heat inside and protects the operator from high surface temperatures.

4. Digital Control Panel At the bottom front, with:

Temperature display (PID controller)

Control buttons & switches

Indicator lights

5. Exhaust/Vent On the top for gases to escape during ashing or heating processes.

Typical Specifications for such a unit:

Temperature range: 200 C to 1200 C (some models up to 1600 C).

Power supply: Single-phase or three-phase AC.

Heating elements: Kanthal or silicon carbide rods embedded in the chamber walls.

Common Lab Uses:

Ash content testing (coal, food, polymers)

Heat treatment of small metal or ceramic samples

Burn-off of organic matter from inorganic materials

Melting and sintering of certain materials
