GSL-1700X-MGI-4 Four-Channel 1700°C Tube Furnace with 25mm Alumina Tubes for High-Throughput Annealing
The GSL-1700X-MGI-4 is engineered to facilitate high-throughput annealing processes by integrating four independent tube furnace modules within a compact footprint. This design enables simultaneous heat treatment of multiple alloy or ceramic samples, optimizing laboratory workflow and throughput. Each module is equipped with a 25 mm outer diameter alumina tube, providing a chemically inert environment suitable for high-temperature applications up to 1700°C.
Temperature control is independently managed for each channel via advanced 30-segment PID controllers displayed on a touch screen interface, ensuring precise thermal profiles with stability better than ±1°C. The system supports continuous operation up to 1600°C at ambient pressure and short-term excursions to 1700°C. Vacuum capability down to 5×10⁻² torr is available optionally, expanding the range of possible experimental conditions.
Key Features
- Four independent tube furnace modules with 25 OD × 22 ID × 460 mm alumina tubes.
