Experimental Vacuum Distillation Furnace for Nonferrous Metal Purification

Product Overview

This vertical vacuum distillation furnace is a specialized laboratory system engineered for the purification and separation of nonferrous metals. Its well-type lifting lid structure and compact footprint make it ideal for small-batch experiments in metallurgical R&D, enabling precise control over temperature and vacuum parameters for reproducible results. The unit is designed to deliver high-purity metal outputs through advanced thermal processing under tightly controlled conditions.

The system achieves high vacuum levels and uniform heating, creating an oxygen-free environment that prevents metal oxidation and enables clean distillation of low-boiling-point elements. Its vertical configuration promotes stable thermal gradients essential for effective separation, making it particularly suited for studying phase equilibrium and optimizing industrial-scale recycling processes. Advanced PID control ensures the furnace maintains setpoints with minimal deviation, even during complex multi-step protocols.

Built with robust industrial-grade components, this system delivers consistent performance under continuous operation. Every unit undergoes rigorous leak testing and temperature uniformity verification to guarantee dependable results in demanding lab settings. Users benefit from minimal maintenance and a compact footprint that fits standard laboratory spaces, providing a reliable platform for cutting-edge material science research.

Key Features

• Advanced Vacuum System: The furnace incorporates a precision mechanical pump and high-integrity sealing design to achieve an ultimate vacuum of 5 Pa with a pressure rise rate of only 3 Pa per hour. This low-leakage environment is crucial for achieving high-purity metal distillation and preventing re-oxidation of volatile elements.
• Multi-Zone Thermal Control: Two independent PID control loops (one heated zone with two control zones) work with a tungsten-rhenium thermocouple to maintain temperature uniformity within ±1°C. Users can create custom thermal profiles for step-controlled distillation of multi-component alloys, ensuring repeatable process outcomes.
• Lift-Off Chamber Design: The electromechanical lid lifting mechanism allows easy access to the internal hot zone and crucible assembly, simplifying sample loading and maintenance. The vertical orientation promotes natural convection within the vacuum, enhancing separation efficiency.
• Programmable Logic Controller: A high-resolution touchscreen interface provides full recipe management, real-time trending of temperature and vacuum, and alarm logging. Operators can store multiple experimental protocols, reducing setup time and ensuring consistency between runs.
• Safety-Centric Engineering: Integrated safety features include over-temperature cutoff, vacuum loss detection, and controlled backfill gas inlet with pressure limitation to 0.05 MPa. All electrical systems are enclosed and protected, meeting laboratory safety standards.
• Durable Hot Zone Construction: The working chamber is fabricated from high-alumina refractory materials with premium heating elements capable of reaching 1400°C repeatedly without degradation. This robust design ensures years of trouble-free service even with frequent thermal cycling.
• Compact and Ergonomic: With a vacuum chamber diameter of 420 mm and height of 450 mm, the system fits easily into typical high-temperature lab rooms while offering sufficient working volume for meaningful batch sizes (80 mm diameter × 100 mm height). Its vertical layout minimizes floor space.
• Flexible Gas Backfill: After the distillation cycle, the chamber can be backfilled with inert gas (up to 0.05 MPa) to cool samples under protective atmosphere, preventing hygroscopic or pyrophoric reactions.
