High-Purity Quartz Glass Tubing: Exceptional Heat Resistance and Versatility

Our high-purity quartz glass tubing, crafted from pure silica, combines superior clarity, durability, and exceptional heat resistance up to 1200°C. Ideal for scientific, industrial, and lighting applications, these tubes deliver exceptional reliability in high-performance environments.

We supply a wide range of tube dimensions — with outside diameters from 2mm to 800mm and rods from 2mm to 45mm. Beyond our standard forms, our advanced processing capabilities allow for custom shapes and configurations to meet the exact needs of your application.

Exceptional Properties and Advantages

• Outstanding Heat Resistance: Operates reliably up to 1200 °C — far exceeding borosilicate glass (300 °C).
• Superior Optical Clarity: Ultra-clear silica composition for high light transmission and precision performance.
• High Chemical Stability: Resistant to most acids and alkalis, ensuring long service life in harsh environments.
• Dimensional Precision: Consistent wall thickness and accurate tolerances for dependable fit and function.
• Custom Processing: Capable of forming, fusing, or machining tubes into bespoke configurations.

Applications

Quartz glass tubing’s purity and durability make it essential in a wide range of technical industries:

• Lighting Industry: Ideal for envelopes in xenon, ultraviolet, and halogen lamp production.
• Scientific Equipment: Suitable for laboratory tubes, thermocouple protection, and analytical apparatus.
• Semiconductor Manufacturing: Used in wafer processing, cleanroom systems, and high-temperature reactors.
• Electrical and Power Applications: Quartz rods provide excellent high-voltage insulation and dielectric strength.
• Industrial Furnaces: Withstands extreme heat for thermal observation and process monitoring.

Quartz Rod Availability

Quartz rods are available in diameters ranging from 2mm to 80mm. These rods maintain the same high-purity silica composition as our tubing, offering outstanding strength, transparency, and electrical insulation. Ideal for semiconductor, optical, and engineering applications.

Quartz Grades Offered

We supply three distinct grades of quartz glass, each offering unique optical and thermal performance characteristics:
