Product Overview
Labotemp Muffle Furnace FMU-13 is a high-temperature laboratory/industrial furnace with a 20 L chamber, designed for thermal processing up to 1700°C (1500°C continuous). The chamber uses HHR polycrystalline mullite fiber and high-temperature alumina insulation. A 12 kW HHR MoSi₂ rod heating system ensures fast heat-up (<40 min), stable temperature uniformity and long service life. FMU-13 is suited to ceramic sintering, metallurgy, crystal growth, annealing, thermal analysis and material testing in universities, R&D centres and industrial labs, and includes programmable control and multiple safety protections.

Key Features

• Chamber & insulation: HHR polycrystalline mullite-fiber chamber with high-temperature alumina fiber insulation for reduced heat loss.
• Temperature: Maximum 1700°C (1500°C continuous rating) with 1°C resolution and ±1°C accuracy.
• Heating system: 12 kW HHR MoSi₂ rod heater for rapid rise time (<40 min) and consistent output.
• Controller: 7” touchscreen PL with PID control, touch temperature setting, Touch/LED display and programmable cycles (0–9999 min).
• Safety: Overtemperature protection, leakage protection and automatic heating cut-off on door opening.

Applications

• Ceramic sintering and advanced ceramics processing.
• High-temperature metallurgy and annealing operations.
• Crystal growth, precision materials research and heat treatment.
• Thermal analysis and material testing in universities, R&D centres and industrial laboratories.
