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.
