GSL-1200X-MH100 Tube Furnace for High Magnetic Field Research
The GSL-1200X-MH100 tube furnace is engineered specifically for experimental research requiring simultaneous application of high temperatures and strong magnetic fields exceeding 10 Tesla. It enables controlled atmosphere processing up to 1100°C, facilitating advanced studies of material behaviors under these combined conditions. The furnace accommodates samples up to 20 mm diameter and 250 mm length within a quartz processing tube, making it suitable for a variety of high-temperature magnetic field experiments.
This model integrates a 10 kW DC programmable power supply delivering regulated output up to 24 VDC, paired with dual spiral-wound molybdenum resistance wire heating elements designed to minimize Lorentz forces in high magnetic environments. The furnace housing is constructed from non-magnetic SS316 austenitic stainless steel with water cooling to maintain surface temperatures below 25°C, ensuring safe operation near sensitive magnet systems. Temperature is precisely managed by a PID controller with 50 programmable segments and an accuracy of ±0.1°C, supported by S-type and T-type thermocouples for process and surface monitoring respectively.
Key Features
- Maximum continuous operating temperature of 1100°C with uniform heating zone of ±5°C over 250 mm length.
- Minimum bore diameter of 100 mm to fit within high magnetic field magnet bores.
- Non-magnetic SS316 furnace case with water cooling to protect magnet and maintain low surface temperature.
- Dual spiral-wound molybdenum resistance wire heating elements optimized to reduce Lorentz force effects.
- PID programmable temperature controller with remote RS-485 communication and safety alarms.
- Quartz processing tube (Ø30 × Ø25 × 1000 mm) with hermetic SS316 flanges and gas inlet/outlet fittings for controlled atmosphere operation.
- Optional vacuum pump available to evacuate residual air down to 50 mtorr for inert atmosphere processing.

It supports studies in physics, materials science, and engineering disciplines where combined thermal and magnetic environments are critical.
Configuration & Operating Notes
The furnace requires an inert gas atmosphere for safe operation of the molybdenum heating elements. A vacuum pump is optionally available to evacuate air from the processing tube prior to gas backfilling. Water cooling is mandatory to maintain safe surface temperatures and protect the magnet. The system includes RS-485 communication for remote monitoring and control. Users should ensure compatibility with their magnet bore size and verify cooling water supply before operation.
