GSL1100X8 1100°C Quartz Tube Furnace with 8.5″ Diameter and Water-Cooled Hermetic Flanges for Controlled Atmosphere CVD Processing
The GSL1100X8 tube furnace is engineered for high-temperature chemical vapor deposition (CVD) applications requiring precise thermal processing of large samples or wafers. Its 8.5-inch diameter quartz tube accommodates sizable substrates, while the 24-inch (600 mm) heating zone provides a uniform temperature environment essential for consistent material synthesis and treatment.
This furnace integrates a single heating zone controlled by a programmable PID temperature controller capable of up to 30 segments, ensuring accurate temperature profiles. The system includes water-cooled stainless steel hermetic flanges that maintain a controlled atmosphere within the quartz tube, supporting processes sensitive to environmental conditions.
Key Features
- Maximum operating temperature of 1100°C with continuous operation between 400°C and 1050°C.
- Effective heating zone length of 600 mm with a ±5°C uniform temperature zone of 200 mm.
- Quartz processing tube with 216 mm outer diameter and 208 mm inner diameter, 1020 mm length.
- Water-cooled hinged stainless steel hermetic flanges with integrated pressure gauge and multiple feedthrough ports.
- Programmable PID temperature controller with dual K-type thermocouples for control and monitoring.
- Double-layer steel casing with cooling fans to maintain surface temperature below 70°C.
- Optional Eurotherm 3000 series temperature controller for enhanced accuracy and LabVIEW-based remote control software.

Configuration & Operating Notes
The furnace requires a water chiller providing ≥10 L/min flow at 5-30°C and 10-60 PSI for flange cooling; a KJ5000 recirculating water chiller is recommended. Optional accessories include a Eurotherm 3000 series temperature controller for enhanced stability and LabVIEW-based remote control software for temperature profile management and data logging. Proper handling of quartz tubes and O-ring seals is necessary to maintain hermetic conditions. Safety precautions should be observed when operating at high temperatures and pressures.
