Annealing furnace FMU-17

calcinationthermalanalysis

Overview
Labotemp Controlled Atmosphere Furnace FMU-17 is a mid-sized laboratory muffle furnace rated to 1200 °C. It combines three-sided resistance heating with PID temperature control to provide stable ramps and ±1 °C accuracy. The vacuum-sealed chamber with inert gas ports supports nitrogen, argon, oxygen and other non-reactive gases for controlled-atmosphere processes. Multi-layer high-purity ceramic fiber insulation and a robust steel shell reduce heat loss for frequent laboratory cycles.

Applications

• Material research and small-batch production
• Ceramic and powder sintering
• Calcination
• Annealing and stress-relief operations
• Carbon material treatment
• Lithium battery material processing
• Ashing and thermal analysis of samples
• Controlled atmosphere material testing and high-temperature R&D processing
