GSL-1750X-60 Bench-Top Vacuum and Atmosphere Tube Furnace with Kanthal Super-1800 Heating Elements
The GSL-1750X-60 tube furnace is engineered for laboratory applications requiring high-temperature processing under vacuum or controlled gas atmospheres. It is particularly suited for sintering new material samples and conducting chemical research where precise temperature control and a clean environment are critical. The furnace accommodates a high purity alumina processing tube with a 60 mm outer diameter, enabling effective containment and uniform heating of samples.
This compact bench-top furnace features Kanthal Super-1800C grade molybdenum disilicide (MoSi2) heating elements, known for their durability and high-temperature capability. The heating chamber is lined with high purity alumina refractory board to ensure thermal efficiency and stability. Vacuum sealing flanges equipped with valves and a vacuum gauge allow for reliable vacuum or gas atmosphere operation, with vacuum levels achievable down to 50 mTorr using a mechanical pump or 10^-5 torr with a turbo molecular pump (vacuum pumps sold separately).
Key Features
- Maximum operating temperature of 1750°C with continuous operation up to 1700°C
- 30-segment programmable SCR digital temperature controller with ±1°C accuracy and PID control

Typical Applications
Ideal for sintering advanced materials, ceramics, and chemical samples under vacuum or controlled atmospheres. Commonly used in materials science, chemical research, and development laboratories requiring precise thermal processing up to 1750°C.
Configuration & Operating Notes
The furnace includes alumina tube blocks to minimize heat radiation inside the tube and vacuum sealing flanges with valves and a vacuum gauge for immediate vacuum operation. Quartz tube blocks are available optionally for cleaner processing and improved vacuum efficiency. The furnace can be optionally controlled via PC using the MTS-02 control module, which must be ordered separately. Users should perform temperature calibration before use to ensure accuracy. Vacuum operation is recommended up to 1500°C for safety. Gas flow rates should be limited to below 200 ml/min to avoid thermal shock. A gas pressure regulator is necessary when using high-pressure gas cylinders to prevent overpressurization.
