Muffle Furnace FMU-20

Muffle Furnace FMU-20

Description:

Labotemp Muffle Furnace FMU-20 is a bench-top box furnace engineered for laboratories requiring reliable high-temperature processing up to 1200°C. Designed as a front-loading laboratory furnace with a 40-liter chamber (300×300×450mm), it features heating elements embedded on three sides for fast, uniform heat distribution and minimal temperature gradient, critical for consistent results in sintering, calcination, ashing, ceramic firing, glass seal firing, wax burnout, and gravimetric analysis workflows.

Built with high-alumina ceramic fiber board insulation and a steel exterior with air-cooling fan, the FMU-20 balances maximum thermal efficiency with a safe-to-touch outer surface. The programmable digital PID temperature controller with 32 segments and ±1°C accuracy ensures precise, repeatable thermal profiles. Overheat protection, power failure auto-resume, and self-tuning PID control with minimal overshoot provide a secure operating environment for demanding daily laboratory use.

Why Choose Labotemp Muffle Furnace FMU-20?

✓ Uniform Heating Performance: Three-sided embedded elements deliver superior temperature uniformity across the full chamber volume
✓ Precise Process Control: 32-segment programmable PID controller with ±1°C accuracy supports complex, repeatable thermal protocols
