GSL-1700X-II-LD Dual Zone Tube Furnace with Independent 12″ Heating Zones, Up to 1700°C Max Temperature
The GSL-1700X-II-LD tube furnace is engineered for advanced laboratory processes requiring controlled thermal gradients, such as functional material preparation and epitaxial film growth via chemical or physical vapor deposition. Its dual heating zones, each 12 inches (300 mm) in length, allow independent temperature regulation to create precise thermal profiles along the tube length.
One zone utilizes molybdenum disilicide (MoSi2) heating elements capable of reaching temperatures up to 1700°C, while the other zone employs silicon carbide (SiC) elements with a maximum temperature of 1400°C. This configuration enables a stable thermal gradient or uniform heating within a 14-inch (300 mm) constant temperature zone when both zones are set to the same temperature below 1500°C.
주요 기능
- Dual independent heating zones with separate digital PID temperature controllers featuring 30 programmable segments for precise ramping and dwell control.
- Zone 1 heated by six U-shaped SiC rods (1500°C grade), operating between 800°C and 1500°C with S-type thermocouple.
- Zone 2 heated by six U-shaped MoSi2 rods (1800°C grade), operating between 800°C and 1700°C with B-type thermocouple.
- Double-layer steel casing with cooling fans and high-purity fibrous alumina insulation for energy efficiency and low external surface temperature.
- Stainless steel vacuum sealing flange with valve and meter included, supporting vacuum and low-pressure operation below 0.02 MPa.
- PID SCR power control with built-in over-temperature alarm and ±1°C temperature accuracy.
- Compatible with alumina tubes of various diameters (50 mm, 60 mm, 80 mm outer diameter) and 1200 mm length.

대표적인 적용 분야
Ideal for preparing functional materials requiring controlled thermal gradients, epitaxial film growth by chemical vapor deposition (CVD) or physical vapor deposition (PVD), and other advanced material synthesis processes under vacuum or low-pressure conditions.
구성 및 작동 안내
The furnace includes a stainless steel vacuum sealing flange with valve and meter. Optional accessories such as flange supports to prevent tube rotation and alternative fittings (KF25 adapter or VCR face seal fittings) for gas supply and vacuum enhancement are available separately.
Operation under vacuum or low pressure (<0.02 MPa) is recommended, with gas flow rates limited to below 200 SCCM to avoid thermal shock. A two-stage pressure regulator must be installed on gas cylinders to maintain safe pressure below 3 PSI. Graphite crucibles should not be used inside the alumina tube. Vacuum operation is safe up to 1500°C.
