Product Usage Guidelines of Capillary Quartz Tubes
Handling & Installation
Handle with Care
Handle spiral quartz tubes gently to avoid impacts or drops that could cause breakage. Use clean gloves to prevent contamination of the surface.
Temperature Control
Do not exceed the maximum operating temperature of 1600°C. Rapid temperature changes should be avoided to prevent thermal shock.
Chemical Compatibility
Avoid contact with alkaline substances (sodium/potassium compounds, water glass, asbestos) at high temperatures, as these will significantly degrade performance.
Maintenance & Storage
Cleaning
Clean with mild detergent and distilled water. For stubborn deposits, use diluted acids (avoid hydrofluoric acid). Rinse thoroughly and dry completely before reuse.
Storage
Store in a clean, dry environment. Use original packaging or cushioned containers to prevent contact with hard surfaces. Avoid stacking heavy items on top of tubes.
Inspection
Regularly inspect for cracks, chips, or discoloration. Replace damaged tubes immediately to prevent system failures or contamination.

FAQ
Q: What are the main advantages of spiral quartz tubes over straight tubes?
A: Spiral quartz tubes offer several advantages: increased surface area in a compact footprint, extended UV light path for better sterilization efficiency, improved heat distribution for IR applications, and enhanced mixing capabilities for laboratory reactions. The spiral design also provides greater structural flexibility while maintaining the excellent thermal and chemical properties of quartz.
Q: What is the maximum temperature that TOQUARTZ® spiral quartz tubes can withstand?
A: Our spiral quartz tubes can withstand continuous operating temperatures up to 1100°C and short-term exposure up to 1600°C. The softening point of high-purity quartz is approximately 1730°C. However, we recommend maintaining a safety margin below these limits for prolonged use, especially for spiral configurations where stress distribution differs from straight tubes.
Q: Are TOQUARTZ® spiral quartz tubes suitable for UV-C transmission applications?
A: Yes, our high-purity spiral quartz tubes offer excellent UV-C transmission (>90% at 254nm wavelength), making them ideal for UV sterilization systems. We can provide specific transmission data for different wavelengths upon request. For UV applications, we recommend our clear fused quartz grade with minimal iron content to maximize UV transmission efficiency.
Q: Can you create spiral quartz tubes with variable pitch or diameter?
A:Yes, we can manufacture spiral quartz tubes with variable pitch or diameter changes along the length. These advanced designs can optimize flow characteristics, heat distribution, or optical properties for specific applications. Such customizations require detailed technical discussions with our engineering team to ensure manufacturability and performance.
Q: Do you offer any surface treatments for spiral quartz tubes?
A: Yes, we offer several surface treatments for spiral quartz tubes, including acid etching for improved adhesion, fire polishing for enhanced optical clarity, special coatings for specific wavelength filtering, and surface dealkalization for improved high-temperature performance. These treatments can be customized based on your application requirements.
