Product overview
The Labotemp Muffle Furnace FMU-13 is a high-temperature laboratory and industrial muffle furnace with a 20 L chamber, designed for thermal processing up to 1700℃ (1500℃ continuous). It combines an HHR polycrystalline mullite-fiber chamber, high-temperature alumina insulation and a 12 kW HHR MoSi₂ rod heating system for rapid heat-up (<40 min), stable operation and good temperature uniformity. FMU-13 is intended for ceramic sintering, high-temperature metallurgy, crystal growth, annealing, thermal analysis and material testing in universities, R&D centres and industrial laboratories, and incorporates programmable control and multiple safety protections.

Key benefits

• Rapid and uniform heating with 12 kW HHR MoSi₂ rod system; heat-up <40 min.
• 20 L chamber increases part throughput for lab-scale batches.
• High-efficiency thermal insulation with mullite chamber and alumina fiber to reduce heat loss.
• Programmable PID control and multi-stage cycles for repeatable profiles plus built-in safety protections.

Features

• HHR polycrystalline mullite-fiber chamber for low heat loss and durability.
• High-temperature capability to 1700℃ (1500℃ continuous), resolution 1℃, accuracy ±1℃.
• 12 kW HHR MoSi₂ rod heater delivering fast, stable heating.
• High-temperature alumina fiber insulation for improved efficiency.
• 7" touchscreen PL controller with PID, programmable cycles (0–9999 min) and real-time temperature curve display.
• Comprehensive safety: over-temperature protection, leakage protection, door-opening heating cut-off, sensor alarm and overshoot setting.
• Optional communication: RS-485 and USB data storage.

Applications

• Ceramic sintering and advanced ceramic processing.
• High-temperature metallurgy and annealing operations.
• Crystal growth, precision materials research and thermal analysis.
• University labs, R&D centres and industrial laboratories requiring controlled, repeatable high-temperature profiles.
