1200C Three Zone Split Vertical Tube Furnace 4 Inch Quartz Tube Stainless Steel Vacuum Flanges

Product Overview

This vertical thermal processing system represents a sophisticated solution for material science laboratories and industrial R&D facilities requiring precise atmosphere control and rapid temperature cycling. By integrating a split-shell design with a vertical orientation, the equipment facilitates efficient sample loading and unloading while optimizing workspace in high-traffic research environments. Its primary value proposition lies in the ability to maintain extreme thermal stability across three independent heating zones, allowing for the creation of precise temperature gradients or extended isothermal regions required for advanced crystal growth and chemical vapor deposition processes.

Targeting sectors such as aerospace engineering, semiconductor development, and solid-state chemistry, this system provides the versatility needed for complex heat treatment recipes. The combination of high-purity quartz tubing and robust vacuum sealing ensures that sensitive materials are processed without contamination. Whether performing rapid quenching tests or steady-state sintering, the unit delivers the repeatability and accuracy essential for generating high-quality research data in both academic and industrial settings.

Constructed with industrial-grade components and a focus on long-term operational reliability, the furnace is designed to withstand the rigors of continuous high-temperature service. The split casing allows for easy maintenance and fast cooling, while the integrated heavy-duty mobile base ensures that the entire system can be repositioned safely within a facility. This investment in premium engineering translates to consistent performance, minimizing downtime and maximizing the throughput of critical research projects where precision is non-negotiable.

Key Features

• Independent Three-Zone Heating Control: The system features three distinct heating zones, each 300mm in length, which can be controlled independently to create custom thermal gradients. This setup is crucial for applications like Bridgman crystal growth or ensuring a highly uniform temperature profile across a 600mm constant heating zone when zones are synchronized.
• Precision Split-Shell Design: The furnace body is engineered with a split-shell configuration that opens lengthwise. This allows users to easily insert or remove the process tube and facilitates rapid cooling of the sample after high-temperature cycles without the need for complex disassembly of vacuum connections.
• Advanced Vacuum Sealing System: Equipped with dual stainless steel vacuum flanges, the unit includes high-quality valves and a vacuum gauge. The top flange features an integrated hook ring, designed specifically for hanging crucibles or samples for quenching experiments, ensuring vertical stability during the heat treatment process.
• High-Purity Fused Quartz Reaction Tube: The standard 4-inch diameter quartz tube provides excellent thermal shock resistance and chemical inertness. This material is ideal for maintaining a high-purity environment under vacuum or flowing gas, allowing researchers to monitor reaction progress visually through the transparent tube.
• Sophisticated PID Temperature Regulation: The MET-certified controller provides 30 programmable segments for precise management of heating rates, cooling rates, and dwell times. Accuracy is maintained within ±1°C, supported by built-in PID auto-tune functions and broken thermocouple protection for unattended safety.
• Robust Thermal Insulation: Utilizing high-quality fibrous insulation, the system is designed for maximum energy efficiency. This material minimizes heat loss and ensures that the exterior casing remains at a safe temperature even during sustained operation at the 1200°C maximum threshold.
• Integrated Safety Features: The system includes over-temperature protection and alarms as standard, allowing for safe overnight operation. The double-layered steel casing incorporates an air-cooling fan system to keep the outer surface temperature below 55°C, protecting lab personnel and surrounding equipment.
• Heavy-Duty Mobile Integration: The entire furnace unit is mounted on a heavy-duty, industrial mobile cart. This allows for easy relocation of the equipment within a facility while providing a stable, vibration-damped platform for sensitive experimental setups.
• Digital Communication Capability: Featuring an RS485 communications port, the furnace can be integrated with external computer systems. This enables remote monitoring, data logging of heating profiles, and automation of complex thermal recipes through Labview-based software environments.
• Expandable Atmosphere Control: Standard 1/4" barbed needle valve fittings allow for the introduction of protective gases. The system can be upgraded with Swagelok fittings or KF25 adapters to accommodate high-vacuum pumps and precise mass flow controllers for CVD applications.
