1200C Four Zone Split Tube Furnace with Touch Screen Control and High Purity Quartz Tube and Vacuum Sealing Flanges

Product Overview

This sophisticated thermal processing system is engineered to provide unmatched precision in high-temperature material research and industrial production. By utilizing a unique four-zone heating architecture, the equipment allows operators to choose between creating a perfectly uniform constant temperature zone or establishing a tailored thermal gradient. This versatility is essential for advanced material synthesis, where specific temperature profiles are required to drive chemical reactions, facilitate crystal growth, or manage phase transitions with exacting detail. The split-furnace design further enhances operational efficiency, allowing for rapid cooling and easy access to the quartz processing tube, making it an indispensable asset for high-throughput laboratory environments.

Designed for demanding R&D cycles and pilot-scale manufacturing, this unit excels in semiconductor diffusion, ceramic sintering, and specialized annealing processes. Its robust construction and advanced insulation materials ensure it can maintain peak temperatures of 1200°C while protecting sensitive laboratory environments and surrounding electronics from heat dissipation. Industries ranging from aerospace and battery technology to solid-state chemistry rely on this system for its ability to deliver repeatable results under vacuum or controlled atmosphere conditions. The integration of high-purity quartz and precision vacuum seals provides a clean, contaminant-free environment for even the most sensitive analytical samples.

Reliability is the cornerstone of this thermal system's engineering. Every component, from the high-purity fibrous alumina insulation to the heavy-duty cooling fans, is selected to ensure structural integrity and performance longevity under continuous operation. The dual-layer steel housing remains cool to the touch even during peak heating cycles, prioritizing operator safety and equipment durability. By combining state-of-the-art touch screen automation with traditional split-furnace reliability, this system offers a professional-grade solution for researchers who require both the power of high-temperature processing and the finesse of multi-zone thermal management.

Key Features

• Independently Controlled Four-Zone Heating: The system features four distinct heating zones arranged in a 150mm-300mm-300mm-150mm configuration, allowing for the creation of precise thermal gradients or a massive 900mm total heated length for large-batch processing.
• Advanced Touch Screen Interface: A centralized high-resolution touch panel integrates four PID controllers, enabling seamless 30-segment programming for heating rates, dwell times, and cooling curves with an accuracy of ±1°C.
• Split-Furnace Engineering for Efficiency: The hinged split-case design allows for rapid opening of the chamber, facilitating faster sample cooling after processing and simplifying the installation or removal of the quartz tube and internal fixtures.
• High-Performance Vacuum Sealing: Equipped with a professional-grade vacuum-sealed flange system featuring a built-in needle valve, mechanical pressure gauge, and ball valve, the unit supports vacuum levels as deep as 10-4 torr with appropriate pumping systems.
• Superior Thermal Insulation: Utilizing high-purity fibrous alumina insulation, the system minimizes energy consumption and prevents heat bleed, ensuring the outer shell remains at a safe temperature while maintaining internal thermal stability.
• Precision Thermocouple Array: Four K-type thermocouples are strategically embedded within the zones to provide real-time, high-accuracy temperature feedback directly to the PID controllers for instantaneous adjustment of thermal profiles.
• Enhanced Safety Protocols: The equipment includes built-in overheating protection and a broken thermocouple alarm system, which automatically shuts down heating to prevent hardware damage or experimental loss during unattended operation.
• Versatile Tube Compatibility: The system is designed to accommodate multiple quartz tube diameters, ranging from 80mm to 130mm, providing researchers with the flexibility to scale sample sizes without investing in entirely new furnace systems.
• Forced Air Cooling System: An integrated double-layer steel case with energy-efficient cooling fans ensures continuous airflow between the inner and outer shells, significantly extending the lifespan of electronic components.
• Industrial PC Connectivity: Featuring an RS485 communication port and dedicated software, the system allows for remote monitoring, data logging, and PC-based control of complex thermal cycles for comprehensive audit trails.
