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

Our high-purity quartz glass tubing, crafted from pure silica, delivers exceptional optical clarity, thermal stability, and chemical durability. Designed to withstand temperatures up to 1200°C, it provides unmatched reliability in demanding industrial, laboratory, and lighting applications.

Available in a broad range of dimensions — with outside diameters from 2 mm to 800 mm and quartz rods from 2 mm to 45 mm — our products are suitable for both standard and custom configurations. Through advanced processing capabilities, we can modify quartz tubes into a variety of shapes and specialised forms to meet precise application requirements.

Key Properties and Advantages

• Exceptional Heat Resistance: Operates reliably up to 1200 °C — far exceeding borosilicate glass (300 °C).
• High Purity and Clarity: Manufactured from ultra-pure silica for superior transparency and optical performance.
• Chemical Durability: Inert to most acids and alkalis, ensuring long-term reliability in corrosive environments.
• Precision Manufacturing: Tight dimensional control for consistent performance across large production runs.
• Versatile Processing: Can be cut, shaped, or fused into custom configurations as required.

Applications

Quartz glass tubing’s exceptional purity and high-temperature resistance make it indispensable across multiple industries:

• Lighting Industry: Used for envelopes in xenon, ultraviolet, and halogen lamps.
• Scientific Research: Suitable for laboratory equipment and analytical instrumentation.
• Semiconductor Manufacturing: Components for wafer processing and high-temperature environments.
• Power Applications: Quartz glass rods provide excellent high-voltage insulation.
• Industrial Furnaces: Heat-resistant tubing for thermocouple protection and process observation.

Quartz Rod Availability

We supply quartz rods ranging from 2 mm to 80 mm in diameter, precision-engineered for applications requiring superior strength, transparency, and insulation. These rods are ideal for semiconductor, electrical, and optical industries.

Quartz Grades Offered

John Moncrieff Ltd provides three distinct grades of high-purity quartz glass, each tailored to specific optical and performance needs:

• JGS1: High UV transmission grade — ideal for ultraviolet and optical applications.
• JGS2: Standard optical grade with excellent visible and infrared transmission.
• JGS3: Infrared-grade quartz — optimised for heat-resistant and high-temperature environments.

John Moncrieff Ltd continues its legacy of Scottish precision engineering, offering custom-engineered quartz glass tubes and rods that meet the most rigorous technical and industrial standards.
