1100°C Dual Zone Split Vertical Tube Furnace with 4 Inch Quartz Tube and Vacuum Sealing Flanges

Product Overview

This high-performance split vertical tube furnace is engineered for advanced thermal processing where precision and accessibility are paramount. By combining dual-zone independent temperature control with a vertical split-hinge architecture, the equipment allows for seamless integration into complex experimental setups, including Physical Vapor Deposition (PVD), Close-Spaced Sublimation (CSS), and Chemical Vapor Deposition (CVD). The system provides a versatile platform for material scientists and industrial researchers who require rapid heating and quenching cycles without compromising atmospheric integrity or vacuum levels. Its vertical orientation is specifically designed to facilitate gravity-assisted processes and vertical sample positioning, which is essential for specialized coating technologies and quenching methodologies.

The core value of this unit lies in its ability to maintain a strictly controlled environment within its four-inch high-purity quartz process chamber. The split-casing design is a significant advantage for users working with pre-assembled experimental configurations or fragile ceramic components, as it allows the heating chamber to be opened lengthwise for easy tube insertion and sample retrieval. This efficiency reduces downtime between experiments and minimizes the risk of damage to the reactor tube. Targeting the material science, semiconductor, and renewable energy industries, the equipment provides a robust solution for synthesizing high-purity nanotubes, thin films, and specialized catalysts.

Built for the rigors of 24/7 industrial R&D, the system is mounted on a heavy-duty mobile cart, ensuring flexibility within the laboratory space. The reliability of this system is backed by high-grade insulation materials and precision-engineered PID controllers that maintain exceptional thermal stability. Whether used for the structural ordering of nitrogen-doped carbon or high-temperature brazing under vacuum, the unit delivers consistent, repeatable results under the most demanding thermal conditions. This equipment represents a critical investment for facilities focused on scaling up material synthesis or perfecting heat treatment protocols with industrial-grade accuracy.

Key Features

• Dual-Zone Independent Control: This system features two separate heating zones, each powered by active 3KW elements. Independent temperature controllers allow users to establish distinct thermal gradients or create a wide, uniform isothermal zone across the total 400mm heating length, providing unmatched flexibility for complex vapor phase depositions.
• Hinged Split-Casing Design: The furnace body is constructed with a high-quality hinge mechanism that allows the entire heating chamber to open lengthwise. This engineering choice facilitates rapid access to the process tube, enables quick cooling, and allows for the easy setup of internal crucibles or monitoring equipment without dismantling the entire vacuum line.
• Precision Atmosphere and Vacuum Integrity: Equipped with stainless steel vacuum flanges and high-temperature O-rings, the furnace maintains high-purity environments. The inclusion of alumina-coated foam ceramic blocks protects the vacuum seals from heat radiation, ensuring leak rates remain below 5 mTorr per minute even at peak temperatures.
• Advanced Safety and Thermal Management: A double-layer steel structure with integrated air-flow cooling keeps the external case temperature below 65°C. This safety feature protects laboratory personnel and prevents ambient temperature fluctuations from affecting sensitive nearby equipment during high-temperature runs.
• High-Purity Alumina Insulation: The internal chamber is lined with premium fibrous alumina insulation enhanced with a specialized surface coating. This maximizes energy efficiency by reflecting heat back into the processing zone while ensuring the heating elements remain protected from chemical vapors, extending the operational lifespan of the unit.
• Programmable PID Instrumentation: For sophisticated thermal cycles, the system utilizes MET-certified controllers offering 30 programmable segments. Users can precisely define heating rates, dwell times, and cooling ramps, with built-in PID auto-tune functions ensuring an accuracy of ±1°C throughout the process.
• Industrial Grade Mobility: The entire furnace assembly is integrated into a heavy-duty, reinforced mobile workstation. This allow the high-temperature unit to be repositioned easily within a facility or docked securely at specialized gas delivery stations, making it an ideal choice for multi-user shared laboratory environments.
• Dual-Method Quenching Capability: The vertical configuration supports both traditional wire-cut free-falling and advanced electromagnetic release quenching. This allows researchers to rapidly freeze high-temperature phases of materials into gas or liquid media, providing critical insights into material phase transitions.
