Product overview
Labotemp Muffle Furnace-03B is a compact laboratory muffle furnace designed for controlled high-temperature processes up to 1000°C. With a 7 L silicon carbide-lined chamber and nickel-chromium heating elements, it delivers consistent thermal distribution for tasks such as material testing, ash analysis, sintering and small-batch heat treatments. The unit integrates a PID control system with 1°C resolution and ±5°C accuracy for repeatable cycles.

Design & safety
The furnace is engineered for safe operation and longevity. The cooled outer shell reduces surface temperature during runs. Built-in protections include automatic power cut and alarm on fault, overcurrent/leakage protection switch, and an external emergency stop. Optional upgrades include touchscreen control, programmable sequences and remote monitoring with real-time data logging.
