24 Inch Three Zone Split Tube Furnace with Optional Quartz Tube and Vacuum Flange System for High Temperature Material Synthesis

Product Overview

This high-performance thermal processing system is engineered for advanced material science research and industrial R&D. Featuring a specialized 24-inch heating length divided into three independently controlled zones, the equipment provides researchers with the flexibility to create precise temperature gradients or maintain an exceptionally long uniform thermal flat zone. The split-able design of the furnace body allows for rapid cooling and easy access to the process tube, significantly increasing throughput for sample annealing, diffusion, and sintering processes in various gas atmospheres.

Optimized for high-purity environments, this unit is widely utilized in the synthesis of advanced materials, such as Ta and Nb-doped MoS2, as documented in peer-reviewed journals like ACS Nano. The system integrates advanced microprocessor-based PID control with high-efficiency insulation to ensure stable performance up to 1200°C. By combining a robust mechanical build with precision electronics, the equipment serves as a cornerstone for laboratories focused on semiconductors, battery research, and nanotechnology, providing the reliability required for sensitive chemical vapor deposition (CVD) and physical vapor deposition (PVD) workflows.

Designed for longevity in demanding industrial environments, the equipment employs a double-layer steel case and energy-saving high-purity fibrous alumina insulation. This construction minimizes heat loss while maintaining a low exterior surface temperature for operator safety. Whether performing routine heat treatments or complex multi-stage synthesis, this system delivers the thermal consistency and atmospheric integrity essential for achieving repeatable, high-quality results in modern materials engineering.

Key Features

• Independent Three-Zone Thermal Management: The 24-inch total heating length is divided into three segments (6" + 12" + 6"), each equipped with its own dedicated controller and K-type thermocouple, allowing for the creation of sophisticated temperature gradients or a maximized constant temperature zone.
• Precision PID Microprocessor Control: Advanced MTE-certified controllers utilize self-tuning PID algorithms to maintain ±1°C accuracy across the entire operating range, effectively eliminating temperature overshooting and ensuring process stability.
• Programmable Thermal Profiles: The system supports up to 30 programmable segments per zone, enabling users to automate complex heating, soaking, and cooling cycles required for specialized material transformations and phase studies.
• Atmospheric Versatility and Vacuum Integrity: Equipped with a pair of SS 304 stainless steel vacuum flanges and double high-temperature silicone O-rings, the furnace can achieve vacuum levels of 10E-2 torr with mechanical pumps and up to 10E-5 torr with turbo molecular systems.
• Superior Thermal Insulation: The interior utilizes energy-saving, high-purity fibrous alumina insulation, which reduces power consumption and ensures rapid heating rates up to 20°C per minute without compromising the structural integrity of the chamber.
• Enhanced Safety and Cooling Design: A double-layer steel case with integrated dual cooling fans ensures that the outer shell remains safe to touch even during prolonged high-temperature operations, while built-in over-temperature and broken-thermocouple protection provide unattended operational security.
• Flexible Split-Hinge Architecture: The furnace body is designed to open on a heavy-duty hinge, facilitating quick placement or removal of quartz tubes and allowing for fast cooling of samples post-process, which is critical for preserving certain material phases.
• Digital Connectivity and Remote Monitoring: An RS485 communications port allows the system to interface with PC-based software for real-time data logging, profile management, and remote monitoring, ensuring comprehensive documentation of research parameters.
• Optimized Heating Elements: Utilizing Fe-Cr-Al alloy elements doped with Molybdenum, the furnace provides consistent radiant heat and extended service life even under continuous operation at 1100°C.
