Solving Critical Challenges with Cylindrical Clear Fused Quartz Tubing

UV Quartz Tube for Water Treatment Systems

Research laboratories require precision components that can withstand extreme conditions while maintaining sample purity.

TOQUARTZ® cylindrical clear quartz tubes serve as reaction chambers, sample holders, and observation windows in critical experimental setups where contamination control and thermal stability are paramount.

Usage Guide for Cylindrical Clear Fused Quartz Tubing

Proper handling and usage of cylindrical clear fused quartz tubing is essential to maximize performance and service life.
Follow these guidelines to ensure optimal results and prevent premature failure.

Handling & Installation

Handle it with care to prevent impacts or drops. Even minor surface damage can significantly reduce mechanical strength and thermal shock resistance. Use clean gloves when handling tubes for high-temperature applications to prevent contamination from skin oils.

Temperature Limits

Do not exceed the maximum operating temperature (1100°C for continuous use, 1450°C for short-term exposure). Exceeding these limits can cause softening and deformation of the quartz material.

Cleaning

Clean tubes thoroughly before high-temperature use. For precision applications, use ultrasonic cleaning with appropriate solvents followed by deionized water rinse. Always wear fine-thread gloves during handling to prevent fingerprints and contamination.

Chemical Compatibility

Quartz is an acidic material and should not contact alkaline substances (such as sodium silicate, asbestos, potassium/sodium compounds) at high temperatures, as this will significantly degrade performance. Avoid hydrofluoric acid contact at all temperatures.

Thermal Cycling

While quartz has excellent thermal shock resistance, gradual heating and cooling are recommended for thick-walled tubes to minimize stress. Avoid direct flame contact that creates extreme localized heating.

FAQ

Q: How does UV transmission differ between standard glass and TOQUARTZ® cylindrical clear fused quartz tubing?

A: Standard borosilicate glass typically blocks most UV radiation below 300nm, while our cylindrical clear fused quartz tubing offers excellent transmission across the UV spectrum, including the critical germicidal range (200-280nm). Our quartz tubes provide ≥85% transmission in the 200-250nm range, making them ideal for UV disinfection systems, photochemical reactors, and analytical instruments.

A: These designations refer to different grades of quartz purity and optical properties. JGS-1 is standard grade (≥99.95% SiO₂) suitable for general applications. JGS-2 is high-purity grade (≥99.98% SiO₂) with improved UV transmission and fewer bubbles/inclusions, ideal for optical and UV applications. JGS-3 is ultra-high purity grade (≥99.995% SiO₂) with exceptional optical homogeneity and UV transmission, used in semiconductor and advanced optical applications.

A: Quartz can be directly sealed to certain materials with compatible thermal expansion coefficients. For most applications, mechanical sealing methods using O-rings, gaskets, or specialized fittings are recommended. We can provide tubes with ground ends or special preparations to facilitate specific sealing requirements. For complex assemblies, we offer technical guidance on appropriate sealing methods based on your application parameters.

A: Wall thickness significantly impacts several performance aspects: 1) Mechanical strength – thicker walls provide greater structural integrity and pressure resistance; 2) Thermal shock resistance – thinner walls generally handle rapid temperature changes better; 3) Optical properties – thicker walls may slightly reduce UV transmission; 4) Heat transfer – thinner walls allow faster heat transfer. Our engineers can help you determine the optimal wall thickness for your specific application requirements.

A: TOQUARTZ® cylindrical clear fused quartz tubing can withstand continuous operating temperatures up to 1100°C and short-term exposure up to 1450°C. The actual temperature limit may vary depending on the specific application, duration of exposure, and mechanical stresses involved.
