Frequently Asked Questions (Muffle Furnace Sourcing Guide)

Q1: How do I choose between a 1200°C, 1400°C, and 1700°C muffle furnace?

Choose 1200°C furnaces (featuring Fe-Cr-Al alloy heating wire) for routine ashing, organic decomposition, and general heat treatment. Choose 1400°C or 1700°C furnaces (featuring Silicon Carbide or Molybdenum Disilicide elements) for advanced ceramic sintering, melting, and high-temperature metallurgical research.

Q2: What safety features are integrated into Qiwei muffle furnaces?

Qiwei muffle furnaces include a double-layer air-cooled shell to keep outer surface temperatures safe, automatic thermocouple break protection, over-temperature cut-off alarms, and door-opening safety switches that instantly cut power when the furnace door is opened.
