GSL-1200X-90B High-Pressure Tube Furnace with Three-Zone Heating, Up to 1200°C and 90 Bar Gas Compatibility
The GSL-1200X-90B is engineered for laboratory applications requiring precise high-temperature treatment under elevated gas pressures. It is ideal for processes involving inert and reactive gases such as argon, nitrogen, hydrogen, carbon monoxide, carbon dioxide, methane, and oxygen, accommodating pressures up to 90 bars. This capability supports advanced material synthesis, gas-solid reactions, and controlled atmosphere experiments.
The furnace incorporates a three-zone internal heating system housed within a robust SS310 alloy vacuum chamber equipped with a water cooling jacket. The chamber dimensions are 220 mm outer diameter, 170 mm inner diameter, and 1200 mm length. A quartz tube (60 mm OD, 50 mm ID) is inserted into the heating zone, which measures 1020 mm in total length with a uniform temperature zone of approximately 450°C ± 2°C. Heating elements consist of FeCrAl resistance wire coated with YSZ, enabling stable operation up to 1200°C.
Key Features
- Supports gas pressures up to 90 bars with a built-in 95 bar safety release valve.
- Three-zone PID temperature control with ±1°C accuracy and 30 programmable segments for heating and cooling profiles.
- Vacuum chamber constructed from 310S alloy with water cooling and slidable SS304 flanges for gas inlet/outlet and vacuum ports.
- Compatible with a wide range of gases including inert, flammable, and oxidizing gases.
- Remote operation via RS485 communication port and included PC software.
- Explosion-proof sliding protection case integrated into the heating vessel.
- Optional multi-channel gas delivery system and gas pressure/flow control available.

Configuration & Operating Notes
The system includes a vacuum chamber with KF40 ports, gas inlet/outlet valves, and a sliding protection case. Optional accessories include a multi-channel gas delivery system and gas pressure/flow control modules. Use of flammable gases requires installation of gas leak detectors and automatic shutoff devices. Operation with flammable gases must only be conducted by trained personnel with proper safety measures.
