OTF-1200X-III-5-C3LVSF Three-Zone 5″ Diameter Tube Furnace with Sliding Flange, Gas Mixer, Vacuum Pump, and 1200°C Max Temperature
The OTF-1200X-III-5-C3LVSF is engineered for laboratory applications requiring precise thermal treatment of materials such as annealing, sintering, and diffusion under various gas atmospheres and vacuum conditions. Its three-zone design allows independent temperature control across a 900 mm heating length, enabling the creation of thermal gradients or uniform temperature zones tailored to specific experimental needs.
This model includes a 5-inch outer diameter fused quartz tube and a sliding flange mounted on rails for convenient sample loading and unloading. The system integrates a corrosion-resistant Pirani capacitance diaphragm vacuum gauge and a 156 L/min double-stage rotary vane vacuum pump, supporting vacuum levels down to 10-2 torr. Optional upgrades include turbo pumps for higher vacuum and PC control modules for automated operation.
Key Features
- Three independently controlled heating zones with PID controllers and ±1°C temperature accuracy.
- Maximum temperature of 1200°C with a maximum heating rate of 20°C/min.
- Sliding flange on an 800 mm rail for easy sample access and handling.
- Corrosion-proof capacitance diaphragm vacuum gauge for accurate vacuum measurement in aggressive gas environments.
- Includes a 156 L/min double-stage rotary vane vacuum pump and stainless steel vacuum accessories.
- Energy-efficient double-layer steel casing with alumina fiber insulation and cooling fans for low surface temperature.
- Three-channel gas mixer and mobile carts for flexible setup and operation.
