Three Zone Quartz Tube Furnace with 3 Channel Gas Mixer Vacuum Pump and Anti Corrosive Vacuum Gauge

Product Overview

This high-performance thermal processing system is engineered for advanced material synthesis and chemical vapor deposition (CVD) applications requiring precise atmospheric control. By integrating a three-zone heating architecture with a sophisticated gas delivery manifold and vacuum monitoring suite, the equipment provides a turnkey solution for complex research and development tasks. Its primary value proposition lies in the ability to create customized thermal gradients or extended isothermal zones, which are critical for the growth of high-quality nanotubes, nanowires, and 2D materials like graphene.

Targeted at specialized R&D laboratories, semiconductor manufacturers, and industrial material science centers, the unit excels in processes such as diffusion doping, annealing, and atmospheric heat treatments. The system's design prioritizes flexibility, allowing researchers to mix up to three precursor gases with high precision while maintaining tight control over internal pressures. Whether utilized for small-batch semiconductor production or academic material exploration, this system ensures consistent, repeatable outcomes across various temperature profiles and chemical environments.

Built for reliability under demanding conditions, the equipment features a robust double-layer steel casing with advanced air-cooling technology, ensuring the exterior remains safe to touch even during long-duration high-temperature cycles. Every component, from the high-purity alumina fiber insulation to the anti-corrosive vacuum sensors, has been selected to provide maximum longevity and operational stability. Users can rely on this equipment for consistent performance in harsh chemical environments, making it a cornerstone for laboratories focused on the next generation of materials science.

Key Features

• Independently Controlled Three-Zone Heating: The system features three distinct heating zones that can be programmed independently, allowing for the creation of precise temperature gradients or an exceptionally long isothermal zone of up to 25 inches, ensuring uniform thermal processing for large or multiple samples.
• Integrated Three-Channel Gas Mixing: A mobile gas delivery cart includes three compact direct-read flow meters and four pressure meters, enabling the simultaneous monitoring and precise mixing of up to three different gases for complex CVD or reactive atmosphere processes.
• Anti-Corrosive Vacuum Monitoring: Equipped with a Pirani Capacitance Diaphragm Gauge featuring a ceramic-coated sensor head, the system provides accurate vacuum measurements even when aggressive or corrosive gases are present, significantly extending the life of the monitoring hardware.
• Advanced PID Automation: Three precision temperature controllers utilize PID automatic control with 30 programmable segments, allowing for meticulous management of heating rates, cooling rates, and dwell times with an accuracy of ±1°C.
• High-Purity Quartz Reaction Environment: The 80mm diameter fused quartz tube provides excellent thermal shock resistance and chemical inertness, serving as a contamination-free reaction chamber that is essential for maintaining the integrity of high-purity material synthesis.
• Splittable Chamber Design: The furnace shell features a splittable cover architecture, which facilitates rapid cooling after processing and allows for the easy installation or replacement of the reaction tube without dismantling the entire heating assembly.
• Comprehensive Safety Suite: Built-in protection mechanisms include overheating alarms, broken thermocouple detection, and over-temperature cut-offs, enabling safe, unattended operation during long-dwell thermal cycles.
• Robust Vacuum Performance: The included 120 L/m rotary vane vacuum pump, coupled with stainless steel vacuum flanges and valves, allows the system to reach and maintain vacuum levels down to 10^-2 torr, with stability over 24-hour periods.
