1200C Sliding Internal Crucible Tube Furnace for Controlled Atmosphere Thin Film Deposition and Material Sublimation Research

Product Overview

This high-performance thermal processing system is engineered for advanced material science applications requiring precise sample movement within a controlled atmosphere. By integrating a sophisticated internal sliding mechanism, the equipment allows researchers to transition samples or sublimation sources through specific temperature gradients without breaking vacuum or atmosphere seals. This capability is fundamental for achieving high-quality Physical Vapor Deposition (PVD) and Dual Vapor Deposition (DVD) results, where the relationship between temperature and position is critical to film morphology and growth rates.

Designed for rigorous industrial R&D environments, the unit facilitates complex heat treatment cycles that demand both high-temperature stability and mechanical versatility. The system serves as a cornerstone for laboratories focused on semiconductor development, nanotechnology, and metallurgical phase studies. Its robust construction ensures that sensitive experiments can be conducted under vacuum or inert gas conditions with repeatable precision, providing the reliability necessary for long-duration experimental protocols.

Built with premium thermal components and a focus on user safety, the equipment delivers consistent performance even under demanding continuous operation. The fusion of advanced PID control and a magnetic drive positioning system allows for non-invasive manipulation of the internal crucible, ensuring that the integrity of the internal environment is never compromised. This unit represents a significant leap in thermal processing flexibility, offering a consolidated solution for evaporation, deposition, and precise thermal profiling.

Key Features

• Integrated Magnetic Sliding Mechanism: This system utilizes a unique dual-magnet drive system where an external magnet controls an internal magnetic block, allowing the sample holder to be moved precisely along the length of the quartz tube. This design enables the user to find the optimal temperature position for evaporation or deposition without manual intervention or vacuum loss.
• Advanced NIST-Certified Monitoring: Each unit is equipped with a NIST-certified precision temperature monitor connected directly to the sample holder via a high-vacuum feedthrough. This ensures that the temperature reported is the actual temperature at the sample site, not just the furnace ambient, providing unparalleled data accuracy for critical thin-film growth.
• Precision PID Temperature Control: The equipment features a 30-segment programmable controller that utilizes proportional-integral-derivative logic to maintain a temperature accuracy of ±1°C. This high level of control is essential for managing the ramp rates and soak times required in delicate material synthesis.
• High-Performance Heating Elements: The furnace utilizes Fe-Cr-Al alloy heating elements doped with Molybdenum (Mo). This specific metallurgical composition offers superior resistance to oxidation and thermal fatigue, ensuring a long service life and rapid heating capabilities up to 1200°C.
• Versatile Atmosphere and Vacuum Control: Equipped with KF25 vacuum ports and 1/4" barb fittings, the system can achieve vacuum levels down to 10-2 Torr with a mechanical pump. This allows for processing under inert gases or specific vacuum pressures, which is vital for preventing oxidation during high-temperature cycles.
• Specialized Thermal Insulation: The tube furnace incorporates two fibrous ceramic tube blocks that effectively block heat radiation from the chamber ends. This engineering choice protects the vacuum flanges and ensures a stable, uniform constant temperature zone at the center of the tube.
• Robust Quartz Componentry: The system includes high-purity quartz tubes and crucibles that offer excellent thermal shock resistance and chemical purity, ensuring that no contaminants are introduced to the sample during processing at temperatures up to 1200°C.
• Comprehensive Safety Systems: Built-in protection modules for over-temperature conditions and thermocouple failure are standard. These features prevent equipment damage and ensure lab safety by automatically cutting power if parameters deviate from the programmed safety envelope.
