Three Zone Tube Furnace with 11 Inch or 15 Inch Quartz Tube and Hinged Flanges for Vacuum Atmosphere Heat Treatment

Product Overview

This high-performance three-zone split tube furnace represents a pinnacle in thermal processing engineering, designed specifically to meet the rigorous demands of material science research and industrial R&D. By integrating a large-diameter quartz process chamber with precision-controlled heating zones, the equipment provides a stable and versatile platform for complex heat treatments. The core value proposition of this system lies in its ability to maintain exceptional thermal uniformity over a significant length, which is critical for the success of delicate chemical vapor deposition (CVD) and annealing processes.

Primary use cases for the unit span across various high-tech sectors, including semiconductor manufacturing, energy storage research, and advanced ceramics. It is particularly effective for large-format wafer annealing (up to 12 inches), diffusion processes, and the synthesis of bulk samples under strictly controlled vacuum or gas atmosphere environments. The equipment is engineered to handle continuous operation at temperatures up to 1100°C, making it a staple for laboratories focusing on nitrogen-doped carbon structural ordering or the development of next-generation catalysts.

Built with heavy-duty industrial components, this system offers unparalleled reliability for high-throughput environments. The inclusion of motorized lid actuators ensures smooth, repeatable access to the heating chamber, reducing the risk of mechanical shock to the quartz tube and improving operator safety. Whether used for academic material synthesis or industrial scale-up studies, the unit delivers consistent, reproducible results under the most demanding thermal cycles, instilling total confidence in the integrity of the processed materials.

Key Features

• Precision Three-Zone Temperature Management: This system utilizes three independent programmable PID controllers to manage separate 300 mm heating zones. This configuration allows for the creation of specific thermal gradients or a broad, highly uniform constant temperature zone of up to 600 mm, ensuring consistent results across large batches or long substrates.
• Large-Format Quartz Process Chambers: Buyers can select between 11-inch and 15-inch outer diameter quartz tubes. These high-purity fused quartz tubes provide excellent chemical inertness and thermal shock resistance, allowing for clear visual monitoring of the sample state during high-temperature reactions without compromising vacuum integrity.
• Automated Motorized Lid Actuation: The furnace features a pair of high-torque motorized actuators that open and close the split-lid assembly. This engineering choice eliminates the physical strain of manual operation and ensures that the heavy furnace lid is positioned with precision, protecting the internal ceramic fiber insulation and the quartz tube from accidental impact.
• Advanced SiC Heating Technology: Equipped with 42 high-performance Silicon Carbide (SiC) heating elements, the unit achieves rapid heating rates up to 10°C/min. These elements are strategically positioned to provide balanced radiant heat, contributing to the system's ability to reach a peak operating temperature of 1200°C for short-duration tasks.
• Hermetic Hinged Flanges for Atmosphere Control: The furnace is fitted with a pair of stainless steel, elastomer-sealed hinged flanges. This design facilitates rapid loading and unloading of samples while maintaining a robust seal for vacuum levels as deep as 10^-4 torr when utilized with a high-capacity turbo pump and appropriate thermal blocks.
• Robust Safety and Cooling Architecture: A double-layer steel casing integrated with forced air cooling ensures that the exterior surface temperature remains below 70°C even during peak operation. This protects laboratory personnel and surrounding equipment while maintaining the internal refractory fibrous alumina thermal insulation's efficiency.
• Customizable Control Options: While standard models feature 30-segment PID control with ±1°C accuracy, the equipment can be upgraded with Eurotherm 3000 series controllers. These optional units provide ±0.1°C precision and advanced RS-485 communication protocols for complex data logging and remote process monitoring in industrial 4.0 environments.
• Integrated Gas and Vacuum Ports: The stainless steel flanges include a comprehensive array of ports, including needle valves, pressure gauges, and KF40 vacuum connections. This allows for seamless integration with gas delivery systems and vacuum pumps, facilitating in-situ temperature measurement and precise atmosphere manipulation.
