High Temperature Rocking Tube Furnace with Quartz Tube and Vacuum Flange for Materials Synthesis

Product Overview

This high-performance rocking tube furnace represents a specialized thermal processing solution designed to address the challenges of sample homogeneity during heat treatment. By integrating a precise mechanical rocking stage with a high-purity quartz reaction chamber, this equipment enables the continuous stirring of materials during the heating or melting phase. This dynamic movement is essential for researchers and engineers who require a more uniform reaction environment than that provided by traditional stationary furnaces, ensuring that precursors and molten phases interact consistently throughout the thermal cycle.

Primarily utilized for the preparation of advanced thermoelectric materials and the growth of 2-dimensional crystals, this system is an indispensable tool in material science and industrial R&D laboratories. The ability to control both temperature and mechanical agitation allows for the synthesis of complex compounds that require delicate phase management. Whether used in vacuum or controlled atmosphere environments, the unit delivers the stability needed for sophisticated chemical vapor deposition (CVD) or heterojunction interface research.

Designed with engineering excellence at its core, the unit features a high-grade alumina fibrous insulation liner that maximizes energy efficiency while maintaining rapid heating and cooling capabilities. The robust stainless steel shell is height-adjustable to accommodate various laboratory setups, providing a stable and reliable platform for long-term experimental runs. This equipment is built to withstand demanding industrial conditions, offering consistent performance and repeatable results for the most critical heat treatment processes.

Key Features

• Programmable Dynamic Rocking Mechanism: The integrated rocking stage is powered by a high-torque 40W DC motor, allowing for an adjustable rocking frequency between 10 and 70 RPM. With a maximum rocking angle of 9 degrees, the system ensures thorough agitation of samples, which is vital for preventing sedimentation and ensuring chemical uniformity in molten salts or powdered precursors.
• Advanced PID Thermal Regulation: The equipment utilizes a sophisticated PID automatic controller with 30 programmable segments. This allows for precise control over heating rates, soak times, and cooling stages, ensuring that the thermal profile strictly adheres to experimental requirements with a temperature accuracy of +/- 1°C.
• High-Purity Fused Quartz Chamber: The processing tube is constructed from high-purity fused quartz, offering exceptional thermal shock resistance and chemical inertness. This transparency allows for real-time visual monitoring of the sample's physical state, while the material's resistance to corrosion makes it ideal for processes involving aggressive vapors like phosphorus and sulfur.
• Energy-Efficient Insulation System: The furnace core is lined with a high-purity Al2O3 fibrous insulation material. This energy-saving design minimizes heat loss to the exterior shell and allows for a maximum operating temperature of 1100°C, while maintaining a continuous working temperature of 1000°C.
• Versatile Vacuum and Atmosphere Control: Equipped with heavy-duty stainless steel vacuum flanges, the unit can be configured with various fitting ports, including barbed hose fittings, KF25 adapters, or Swagelok connectors. This flexibility allows users to achieve vacuum levels as low as 50 m-torr with a mechanical pump or 10^-5 torr with a turbomolecular system.
• Automated Process Safety: Built-in protection features include automated shut-off protocols for over-temperature conditions and broken thermocouples. These safety measures protect both the equipment and the valuable samples from thermal runaway or sensor failure during unattended operation.
• Adjustable Height Chassis: The stainless steel furnace body is mounted on a height-adjustable support structure. This design consideration ensures that the equipment can be integrated into existing lab benches or aligned with external gas delivery and exhaust systems with ease.
• Precision Time Management: The rocking station includes a digital timer adjustable from 1 to 1199 minutes, or it can be set for continuous operation. This level of control allows researchers to synchronize the physical movement of the sample perfectly with specific segments of the thermal profile.
