GSL-1750X-S Compact Vacuum Tube Furnace with 1750°C Max Temperature and 60mm OD Alumina Tube
The GSL-1750X-S vacuum tube furnace is engineered for laboratory research requiring high-temperature sintering of novel materials under vacuum or controlled gas environments. Its compact footprint and integrated vacuum flanges enable efficient processing of samples within a 60mm outer diameter alumina tube, ensuring chemical inertness and thermal stability during experiments.
This furnace achieves continuous operation up to 1720°C and can reach a maximum temperature of 1750°C for short durations. Temperature control is managed by a high-precision SCR digital controller with 30 programmable segments, allowing fine-tuned heating and cooling profiles with ±1°C accuracy. The double-layer steel casing with internal air cooling fans maintains safe external temperatures below 60°C.
Wichtigste Merkmale
- High-purity alumina tube (54mm ID, 60mm OD, 790mm length) suitable for vacuum and low-pressure gas atmospheres.
- Four Kanthal Super-1800 MoSi2 heating elements (270mm length) providing uniform heating.
- 30-segment programmable SCR temperature controller with ±1°C accuracy and built-in over-temperature protection.
- Vacuum flanges with double silicone high-temperature O-rings, needle valves, and vacuum gauge included for immediate use.
- Maximum heating and cooling rates of 10°C per minute.
- Double-layer steel casing with air cooling fans to keep external temperature safe.
- RS485 communication port for optional PC control with an additional MTS-02 control module.

Typische Anwendungsbereiche
Ideal for sintering and heat treatment of advanced ceramics, metals, and chemical compounds under vacuum or controlled atmospheres in research laboratories. Suitable for material development, chemical synthesis, and thin film processing requiring precise temperature control and high purity environments.
Hinweise zur Konfiguration und zum Betrieb
The furnace includes a set of vacuum flanges with double silicone O-rings, needle valves, and a vacuum gauge for immediate vacuum operation. Four fiberous ceramic tube blocks are supplied to reduce heat radiation inside the tube and must be properly installed before heating. For enhanced tube support at high temperatures, additional tube supports are recommended (sold separately).
Optional accessories include a PC control module (MTS-02) for remote operation, digital vacuum gauges, flow meters, and mobile carts for easy placement. Users must ensure gas input pressure is regulated below 3 PSI with continuous flow to prevent damage. Vacuum operation is recommended only up to 1500°C for safety.
