Quartz Capillary Tube
quartz capillary tube is a precision-made optical component crafted from high-purity fused silica or synthetic quartz, designed for applications requiring extreme thermal stability, chemical resistance, and optical clarity. These tubes are available in diameters ranging from 0.1 mm to 3.5 mm, with ultra-thin walls (e.g., 0.01 mm) to minimize light diffraction. Key Specifications: Material: Fused silica (99.99% purity) or synthetic quartz, ensuring high UV/IR transmission and low thermal expansion. Dimensions:Standard diameters: 0.1–3.5 mm (custom sizes available). Length: Typically 70 mm (open-ended, with a closed end for sample containment). Packaging: Sold in bundles (e.g., 25 pieces for ≤2.0 mm, 10 for 3.5 mm) Applications: Laser systems: For beam guidance and light transmission. Spectroscopy: As sample cells or flow channels. Microfluidics: In lab-on-a-chip devices for chemical analysis. Technical Advantages: High-temperature resistance: Operates continuously at 1200°C (short-term up to 1500°C). Chemical inertness: Resistant to acids/alkalis (except hydrofluoric acid). Optical clarity: Minimal light scattering due to polished surfaces. Suppliers & Customization: Standard models: Available from suppliers like Capillary Tube (CTS) and Nanyang Kylin. Custom options: L-shaped, U-bent, or large-diameter tubes (e.g., 300 mm) for specialized reactors. |
