GSL1200XIII6 1200°C 3-Zone Tube Furnace with 6″ Diameter Quartz Tube and Touch Screen Control
The GSL1200XIII6 tube furnace is engineered for laboratory applications requiring precise thermal processing of samples within a controlled atmosphere or vacuum environment. Its solid tube design accommodates quartz tubes up to 6 inches (150 mm) in diameter, making it suitable for a variety of material treatments such as annealing, sintering, and chemical vapor deposition under low pressure conditions.
This furnace features three independently controlled heating zones totaling 700 mm in length, enabling uniform temperature distribution and flexible temperature profiling. The maximum achievable temperature is 1200°C for short durations, with continuous operation rated up to 1100°C. Temperature control is managed via a 7-inch touch screen panel with PID automatic control and auto-tuning, supporting up to 50 programmable segments and preset temperature curves for reproducible processes.
Key Features
- Three-zone heating with precise temperature control and ±0.2°C accuracy using K-type thermocouples.
- Touch screen interface with one-click start/stop and automatic temperature data recording stored for one month.
- Energy-efficient high-purity alumina fiber insulation with aluminum oxide coating for extended furnace lifespan.
- Compatible with quartz tubes of various diameters (80, 100, 130, 150 mm) and optional vacuum-sealed stainless steel flanges for controlled atmosphere processing.
- Maximum heating rate of 10°C per minute and continuous operation at 1100°C.
- Optional computer software available for temperature curve control and data export.
- Supports vacuum levels down to 50 mTorr with mechanical pumps and up to 10^-6 Torr with turbopumps (vacuum components sold separately).

Configuration & Operating Notes
The furnace includes a touch screen control panel and power cable (plug optional). Quartz tubes, vacuum-sealed stainless steel flanges, temperature calibrator kits, and computer software for temperature curve control are available as optional accessories. When operating under vacuum or controlled atmosphere, ensure proper installation of two-stage pressure regulators to maintain gas pressure below 3 PSI for safety. The furnace should be powered from an independent supply within ±8% voltage variation and kept away from high magnetic field equipment and conductive powders. Users must implement appropriate safety measures when processing flammable, explosive, or toxic gases, as the manufacturer does not recommend such applications.
