1200°C High Temperature 4 Inch Tube Furnace with Sliding Flange for CVD Systems

Product Overview

This high-performance thermal processing system is a specialized solution designed for advanced material synthesis and chemical vapor deposition (CVD). By integrating a large-diameter quartz tube with a versatile sliding flange mechanism, the equipment provides researchers with an adaptable platform for precision heat treatment. The core value proposition lies in its ability to facilitate rapid sample transitions and maintain stable thermal environments up to 1200°C, making it a cornerstone for laboratories focused on thin-film coatings, nanotechnology, and semiconductor development.

Optimized for reliability, this unit is widely utilized across the electronics, aerospace, and energy sectors. It serves as a primary tool for developing next-generation materials like graphene and carbon nanotubes, where atmospheric control and thermal uniformity are non-negotiable. The robust construction ensures that high-purity results are achieved consistently, even when the system is subjected to repeated heating cycles under vacuum or controlled gas conditions.

Engineered for demanding R&D environments, the system prioritizes both performance and operational safety. From the precision-machined water-cooling flanges to the intelligent safety interlock mechanism, every component is selected to minimize experimental risk and maximize throughput. This equipment represents a significant investment in laboratory productivity, offering the durability required for long-term industrial research and the precision necessary for cutting-edge scientific discovery.

Key Features

• Advanced Slidable Flange System: The right-side flange is mounted on a sliding rail assembly, allowing operators to push or pull samples in and out of the hot zone with minimal effort. This engineering choice is critical for rapid cooling requirements and significantly streamlines the sample loading process, reducing the risk of contamination or thermal shock to the quartz tube.
• Precision PID Thermal Control: Equipped with a digital controller featuring self-tuning functionality and 30 programmable segments, the system maintains a temperature stability of ±1°C. This level of accuracy is essential for repeatable CVD growth and delicate annealing processes where even minor fluctuations can compromise material properties.
• High-Integrity Vacuum and Gas Management: The system supports low-pressure environments and complex gas atmospheres. The left flange includes four Swagelok fittings for gas inlets, while the right flange features a KF25 vacuum port and an anti-corrosive capacitance diaphragm gauge, providing the comprehensive monitoring required for high-purity vacuum processing.
• Integrated Water-Cooling Protection: To preserve the integrity of the sealing O-rings during high-temperature runs, the flanges are designed with internal water-cooling channels. This feature ensures that the vacuum seal remains tight even when the furnace is operating at its maximum rated temperature of 1200°C.
• Safety-First Split Cover Design: The furnace housing features a split-cover architecture with an integrated safety interlock. If the cover is opened during operation, power to the heating elements is immediately disconnected, protecting the operator and preventing accidental damage to the internal components.
• Optimized Constant Temperature Zone: The heating architecture is designed to provide a 100mm constant temperature zone within a 440mm total heating area. This ensures that samples are subjected to uniform thermal profiles, which is a prerequisite for achieving homogenous thin-film deposition across the substrate surface.
• Large Diameter Processing Tube: The 4-inch (100mm ID) quartz tube allows for the processing of larger substrates or multiple samples simultaneously. This capacity is vital for research that aims to scale from small-scale discovery to pilot-level material production.
• Intelligent Monitoring and PC Integration: With optional Labview-based software and WiFi control capabilities, users can remotely manage heat-treatment recipes, record real-time data, and plot thermal profiles, providing a digital audit trail for sensitive industrial experiments.
