Labotemp Muffle Furnace FMU-13 is a high-temperature muffle furnace engineered for demanding laboratory and industrial thermal processing to 1700°C (1500°C continuous). This 20 L lab muffle furnace combines HHR polycrystalline mullite-fiber chamber, high-temp alumina insulation and a robust HHR MoSi₂ rod heating system for rapid heat-up (<40 min), excellent uniformity and durable performance.
Designed as a high-efficiency furnace for ceramic sintering, metallurgy, crystal growth, annealing, thermal analysis and material testing, FMU-13 suits universities, R&D centres and industrial labs. Built for low maintenance and safe operation (over-temp, leakage, door cut-off), it integrates easily into lab workflows and is supported by Labotemp as an experienced furnace manufacturer and furnace supplier.
Why choose Muffle Furnace FMU-13?
✓ Fast, uniform heating: MoSi₂ rods; <40 min to temperature.
✓ Large-capacity lab furnace: 20 L for higher throughput.
✓ High-efficiency construction: Mullite chamber + alumina insulation.
✓ Safe & Programmable: Multi-stage programs and safety protections.
