High-Purity Fused Quartz Tubes
Engineered for superior performance in semiconductor, optical, and high-temperature industrial applications.
KEY FEATURES & BENEFITS
- Exceptional Thermal Stability
With a softening point over 1700°C and an extremely low coefficient of thermal expansion (CTE), our tubes maintain structural integrity and resist severe thermal shock in extreme heat environments.
- Ultra-High Purity Levels
Available in SiO₂ purity levels up to 99.995%. Our quartz prevents contamination in sensitive processes, making it the ideal choice for semiconductor manufacturing and high-purity laboratory work.
- Superior Optical Transmission
Offers excellent light transmission from deep ultraviolet (UV) to the infrared (IR) spectrum, perfect for applications in UV lamps, sight glasses, and advanced optical systems.
- High Chemical Resistance
Chemically inert to most acids, solvents, and corrosive agents at high temperatures. This ensures a long service life and maintains the integrity of your processes.
APPLICATIONS
Built for the World's Most Demanding Industries
Semiconductor Processing
Our high-purity quartz tubes provide an ultra-clean and stable environment essential for critical wafer fabrication processes, including etching, oxidation, chemical vapor deposition (CVD), and diffusion furnaces.
Optical Fiber Manufacturing
Used as the core manufacturing tube for optical fiber preforms. Our synthetic quartz guarantees minimal hydroxyl (OH) content (<1 ppm) for the production of low-loss, high-performance optical fibers.
Industrial Heating & Furnaces
The perfect material for furnace process tubes, thermocouple protection sheaths, and radiant heating elements. Its outstanding thermal shock resistance and high-temperature strength ensure reliability and efficiency.
UV Sterilization & Lamps
We offer specialty synthetic quartz with maximum transparency in the UVC spectrum. This makes it the essential material for high-output UV germicidal lamps used in water, air, and surface purification systems.

FREQUENTLY ASKED QUESTIONS
Frequently Asked Questions
What is the difference between Fused Quartz and Synthetic Fused Silica?
Fused Quartz is made by melting high-purity natural quartz crystal, making it excellent for most high-temperature applications. Synthetic Fused Silica is produced from chemical precursors, resulting in even higher purity and superior optical transmission, which is critical for semiconductor and deep-UV applications.
What are your standard lead times?
Standard stock items typically ship within 1-3 business days. Lead times for custom-fabricated orders vary based on complexity and quantity but generally range from 2 to 4 weeks. Please contact us for a precise schedule for your order.
Can you fabricate tubes with custom end-fittings or special shapes?
Yes. We have extensive capabilities in cutting, grinding, flanging, and welding quartz. We can fabricate complex components based on your technical drawings and specifications.
