Seven Zone 1200C Split Tube Furnace with Precision Temperature Controller and Quick Flange Vacuum System

Product Overview

This high-performance thermal processing system is engineered for advanced material science and industrial R&D applications that require precise control over temperature profiles and gradients. By utilizing a unique seven-zone heating architecture, the equipment allows researchers to establish either an exceptionally long constant temperature zone or a highly specific stepped thermal gradient. This versatility makes the unit an essential tool for complex processes such as chemical vapor deposition (CVD), crystal growth, and sophisticated annealing cycles where standard single-zone furnaces fail to provide the necessary spatial temperature resolution.

Designed with the rigors of modern laboratory environments in mind, this system integrates a large-diameter quartz process tube with a split-furnace design for easy sample loading and tube maintenance. The separation of the heating chamber from the electronic control unit ensures long-term component reliability and simplifies the integration into existing laboratory workflows or glovebox environments. Target industries include semiconductor manufacturing, battery technology development, and high-performance ceramics research, where consistency and repeatability are non-negotiable.

Built for demanding 24/7 industrial and academic cycles, this unit provides unparalleled thermal stability and operator safety. The robust structural engineering, combined with advanced high-purity fibrous alumina insulation, ensures that energy efficiency is maximized while external surface temperatures remain safe for personnel. Users can rely on this equipment for critical path experiments where the integrity of the thermal environment directly correlates to the quality of the resulting material data.

Key Features

• Seven Independent Heating Zones: The equipment features seven distinct 150 mm zones that can be programmed independently. This allows for the creation of a massive 35-inch constant temperature zone or a precise thermal gradient across the 42-inch total heating length, offering unmatched flexibility for vapor transport and localized heating experiments.
• Large Diameter Processing Chamber: Standardized with a 5-inch (130mm) OD quartz tube, the unit is engineered to accommodate substantial batch sizes or large-scale component heat treatments. The versatile design also supports various tube sizes from 1 inch to 4 inches, allowing the laboratory to adapt the system to specific project requirements.
• Pneumatic Lift Support Mechanism: To ensure ease of use and prevent operator fatigue, the split-cover is supported by heavy-duty compressed air springs. This allows for smooth, controlled opening and closing during tube replacement or specimen loading, protecting the delicate quartz components from accidental impact.
• Advanced Touch Screen PID Control: The system is managed via a centralized touch-screen interface that regulates all seven zones simultaneously. Users can save up to 10 unique heat treatment programs, each containing 30 segments, ensuring absolute repeatability between different experiment batches.
• High-Grade Thermal Metallurgy: Utilizing 1300ºC grade Fe-Cr-Al Alloy elements doped with Molybdenum, the furnace provides rapid heating rates and superior longevity compared to standard heating wires. These high-grade elements are specifically chosen for their resistance to oxidation and thermal fatigue at high operating temperatures.
• Efficiency-Focused Insulation: The interior is lined with energy-saving high-purity fibrous alumina. This high-performance refractory material minimizes heat loss and allows the furnace to maintain a cold outer shell through its double-layered steel case with integrated air-cooling technology.
• Simplified Vacuum Sealing: Equipped with stainless steel quick-assembling flanges and an anti-corrosive digital vacuum gauge, the system allows for rapid vacuum setup and breakdown. The inclusion of needle valves and a K25 port ensures the system is ready for immediate integration with vacuum pumps and gas delivery manifolds.
• Durable Safety Protocols: Built-in protection for overheating and broken thermocouples ensures the system automatically shuts down in the event of a technical failure, safeguarding both the equipment and the valuable samples inside the chamber.
