High Purity Quartz Tubes and Quartz Boats for High Temperature Laboratory and Industrial Applications

Product Overview

These high-purity quartz tubes and boats are vital components for any high-temperature laboratory or industrial system. Manufactured from premium-grade silica, they exhibit exceptional thermal stability, chemical inertness, and optical clarity, making them the preferred choice for rigorous thermal processing applications where contamination must be avoided and precise control is required. Their robust construction ensures reliable operation under continuous use at elevated temperatures. Unlike metallic or ceramic alternatives, these quartz components offer superior chemical compatibility and do not outgas at high temperatures.

Engineered to meet the demands of tube furnaces, semiconductor fabrication, and chemical processing reactors, these accessories provide a clean, inert environment for samples and reactions. The ultra-high purity of the quartz material prevents catalytic side reactions and metallic ion leaching, safeguarding the integrity of sensitive experiments and production batches. From academic research to high-volume manufacturing, they deliver consistent, reproducible results.

With a proven track record in demanding applications worldwide, these quartz components are built for longevity. Advanced manufacturing techniques guarantee tight dimensional tolerances and exceptional surface quality, while the inherent properties of fused silica—low thermal expansion and superior thermal shock resistance—eliminate the risk of fracture during rapid heating and cooling cycles. This reliability translates to reduced downtime and lower total cost of ownership.

Key Features

• High Purity Silica Material: Made from top-grade silicon dioxide with minimal impurities, these quartz components prevent metal ion contamination in sensitive processes such as semiconductor manufacturing and catalytic research.
• Superior Thermal Stability: With a softening point around 1730°C, the quartz can withstand long-term use at 1100°C and short-term exposure up to 1450°C, maintaining structural integrity in high-temperature environments.
• Excellent Thermal Shock Resistance: The extremely low thermal expansion coefficient enables the material to tolerate sudden temperature changes—heating to 1100°C followed by immersion in room-temperature water does not cause cracking, far outperforming ordinary glass.
• Outstanding Chemical Resistance: Resistant to virtually all acids except hydrofluoric acid, the quartz material offers acid resistance 30 times that of ceramics and 150 times that of stainless steel, ensuring long-term corrosion resistance even in aggressive chemical environments. This makes them suitable for use with harsh reaction media including strong acids, bases, and oxidizing agents.
• Broad-Spectrum Optical Transmission: With visible light transmittance exceeding 95% and UV transmittance above 80%, these quartz components are ideal for optical experiments, photochemical studies, and UV sterilization systems.
• High Electrical Insulation: The electrical resistance is approximately 10,000 times that of ordinary glass, providing reliable insulation at elevated temperatures, essential for electrical heating and laboratory safety.
• Customizable Dimensions: Tubes and boats are available in a wide range of standard sizes, and custom machining is available to meet specific furnace or process requirements, ensuring a perfect fit for any setup.
• Robust Manufacturing: Precision ground and polished surfaces ensure uniform wall thickness and smooth finishes, improving thermal uniformity and making handling and cleaning easy.
• Long Service Life: The robust quartz construction withstands thousands of thermal cycles without cracking or devitrification, minimizing downtime and replacement costs in high-usage environments.
