GSL-1700X-XX-III Three-Zone Tube Furnace with Alumina Tube, Up to 1700°C
The GSL-1700X-XX-III is engineered for laboratory applications requiring controlled atmosphere heat treatment at high temperatures. It is particularly suited for processes demanding precise thermal profiles and uniform heating over extended lengths, such as materials synthesis, sintering, and annealing under gas or vacuum conditions.
This tube furnace incorporates three independently controlled heating zones spanning a total length of 610 mm, enabling a uniform temperature zone of 300 mm at 1600°C. The furnace accommodates alumina tubes with outer diameters of 50, 60, or 80 mm and a length of 1200 mm, providing flexibility for various sample sizes and process requirements.
Key Features
- Maximum operating temperature up to 1700°C with rapid heating (under 1 hour) and continuous operation up to 1650°C.
- Three-zone heating with 14 molybdenum disilicide (MoSi2) elements for stable and uniform temperature control.
- Double-layer steel casing with air cooling maintains surface temperature below 70°C for safe operation.
- Water-cooled stainless steel flanges with hermetic sealing, including gas inlet/outlet ports and KF25 vacuum connection.
- Programmable PID temperature controllers with 30 segments, ±1°C accuracy, and safety interlocks for over-temperature and thermocouple failure protection.
- Choice of Type B (Pt-Rh) thermocouples for accurate high-temperature measurement.
- Optional Eurotherm 3000 series controller and LabVIEW-based software for advanced temperature profile management and remote control.
