Muffle furnace FMU-12

annealingthermalheat treatment

Overview
Labotemp Muffle Furnace FMU-12 is an ISO- and CE-certified laboratory electric muffle furnace with a 12 L chamber, designed for processes up to 1700℃. It combines an HHR polycrystalline mullite-fiber chamber, high-temperature alumina fiber insulation and HHR MoSi₂ rod heating for rapid heat-up, stable thermal uniformity and extended service life. The integrated 7" touchscreen PL controller provides PID regulation, 0–9999 min programmable cycles and 1℃ resolution for repeatable temperature control.

Applications

• Ceramics sintering and ceramic processing
• Metallurgy and materials research
• Crystal growth and annealing
• Thermal analysis and precision heat treatment
• University, R&D and industrial laboratory workflows

Key benefits

• Precise digital control via 7" touchscreen PL with PID and 1℃ resolution.
• Fast, uniform heating using 10 kW HHR MoSi₂ rod heaters and optimized insulation (rise time <40 min).
• Programmable multi-stage cycles with built-in safety protections and alarms for reliable operation.

Features

• Maximum control temperature: 1700℃ suitable for high-temperature research and processing.
• 10 kW HHR MoSi₂ heating system for rapid ramp-up and stable long-term performance.
• HHR polycrystalline mullite fiber chamber with high-temperature alumina fiber insulation to reduce heat loss.
• 7" touchscreen PL controller: PID control, programmable 0–9999 min, data curve display and 1℃ resolution.
