GSL-800X-MH100 Tube Furnace with 100 mm ID for Controlled Atmosphere Heating up to 800°C under High Magnetic Fields
The GSL-800X-MH100 is engineered to facilitate advanced material property studies in environments subjected to strong magnetic fields greater than 10 Tesla. It accommodates a quartz processing tube with a 100 mm inner diameter and a length of 1000 mm, providing a spacious heating zone of 750 mm length. This setup enables precise thermal treatment under controlled atmospheres up to 800°C, ideal for research requiring stable high-temperature conditions within magnetic fields.
The furnace incorporates a non-magnetic SS316 austenitic steel case to minimize magnetic interference, complemented by water cooling to maintain surface temperatures below 70°C. Its dual spiral-wound molybdenum resistance wire heating elements are designed to reduce Lorentz forces, ensuring stable operation under magnetic influence. Temperature is regulated by a Eurothermo-3000 PID controller with ±0.1°C accuracy, supporting up to 50 programmable segments and remote communication via RS-485.
Key Features
- Maximum continuous operating temperature of 800°C with uniform heating zone ±5°C over 250 mm length.
- 15 kW DC programmable power supply delivering 0-24 V output for precise heating control.
- Quartz processing tube (Ø100 mm OD × Ø90 mm ID × 1000 mm length) with SS316 flanges for hermetic sealing.
- Water-cooled furnace housing to maintain safe surface temperatures during operation.
- Integrated safety monitor to cut power if tube surface temperature exceeds 70°C.
- Compatible with magnets having a minimum bore diameter of 200 mm.
- Steel rigger included for safe and convenient lifting of the tube assembly.
