Product Overview

This high-performance split-tube thermal processing system represents a pinnacle of engineering for material science and industrial R&D laboratories. By integrating a dual-zone heating configuration with a split-hinge chassis, the equipment allows researchers to achieve rapid heating rates up to 1200°C while maintaining the flexibility to create precise thermal gradients. The primary value proposition of this unit lies in its ability to manage independent temperature profiles across two distinct zones, which is critical for complex chemical vapor deposition (CVD) processes and high-purity material synthesis. Whether used for the growth of nanowires or the calcination of advanced ceramics, this system delivers the stability and control required for repeatable scientific results.

The equipment is specifically engineered for versatile applications in semiconductor research, metallurgy, and nanotechnology. By utilizing a high-purity fused quartz process tube and a sophisticated vacuum sealing assembly, the system provides a pristine environment for heat treatment under controlled atmospheres or vacuum conditions. The target audience includes academic researchers and industrial engineers who demand a reliable, easy-to-load furnace that does not compromise on thermal uniformity. The industrial-grade build quality ensures that this unit can operate continuously at 1100°C, making it a dependable workhorse for demanding laboratory environments where uptime and precision are paramount.

Confidence in this system is backed by advanced microprocessor-based control systems and a robust structural design. The combination of dual-layer steel casing and high-purity fibrous alumina insulation ensures that energy efficiency is maximized while the exterior surface remains safe to touch. Every component, from the Fe-Cr-Al alloy heating elements doped with Molybdenum to the precision-machined stainless steel flanges, is selected for its ability to withstand the rigors of high-temperature cycling. This unit is not merely a furnace but a comprehensive thermal solution designed to support the next generation of material breakthroughs with consistent, high-precision performance.

Key Features

• Dual-Zone Independent Temperature Control: The system features two independently controlled heating zones, each equipped with its own dedicated thermocouple and PID controller. This allows for the creation of steep thermal gradients or an extended constant temperature zone by synchronizing the setpoints, providing unmatched flexibility for CVD and vapor phase transport experiments.
• Precision Microprocessor-Based PID Regulation: Two digital controllers manage the heating process with 30 programmable segments each. This allows for meticulous control over heating rates, cooling rates, and dwell times, utilizing a self-tuning function to prevent temperature overshooting and ensure a stability of ±1°C.
• Optimized Split-Chassis Engineering: The furnace body is designed with a hinged split-opening mechanism, allowing for rapid access to the quartz tube and sample area. This design facilitates easy tube installation, sample loading, and faster cooling periods compared to traditional solid-body tube furnaces.
• Advanced Vacuum Sealing Assembly: Each unit comes standard with a pair of 304 stainless steel vacuum flanges featuring double high-temperature silicone O-rings. The assembly includes a needle valve, pressure gauge, and KF25 port, capable of reaching vacuum levels of 10^-2 torr with mechanical pumps and 10^-5 torr with molecular systems.
• High-Efficiency Thermal Insulation: Utilizing energy-saving high-purity fibrous alumina liners and a specialized Al2O3 coating, the equipment minimizes heat loss and extends the service life of the internal components. This insulation ensures rapid ramp-up times and superior thermal retention during long dwell cycles.
• Enhanced Safety and Cooling Systems: A double-layer steel case design integrates two high-velocity cooling fans to maintain low surface temperatures. Integrated safety protocols include over-temperature protection, thermocouple break protection, and audible alarms for unattended operation.
• Versatile Process Tube Options: The system supports fused quartz tubes in 60mm, 80mm, or 100mm outside diameters. This versatility allows labs to scale their throughput or accommodate different sample sizes without needing to invest in entirely separate furnace systems.
• High-Performance Heating Elements: The heating elements are constructed from a specialized Fe-Cr-Al alloy doped with Mo, specifically chosen for their resistance to oxidation and their ability to maintain mechanical integrity at temperatures approaching 1200°C.
• Digital Connectivity and Data Logging: An RS485 communication port is standard, enabling the system to be operated via PC. With optional software modules, users can edit profiles, record real-time data, and manage heat-treatment recipes remotely for better audit trails and research documentation.
• Robust Atmosphere Control: The inclusion of ceramic thermal blocks and high-quality sealing components allows the furnace to operate under vacuum or low-pressure (<0.2 bar) inert gas environments, such as Nitrogen or Argon, ensuring high-purity processing.
