\"\"Quartz Capillary Tubes are precision-engineered tubular components manufactured from high-purity fused silica. Known for their exceptional dimensional accuracy, excellent optical transmission, low thermal expansion, and outstanding chemical resistance, quartz capillaries are widely used in optical communication, microfluidics, analytical instruments, biomedical devices, semiconductor equipment, and scientific research.<\/p>\n

Compared with conventional glass capillaries, fused silica capillary tubes offer superior thermal stability, higher purity, and broader optical transmission from ultraviolet to infrared wavelengths. These characteristics make them particularly suitable for applications requiring precise fluid control, optical alignment, laser transmission, and operation in harsh environments.<\/p>\n

Our quartz capillary tubes are available in a wide range of inner diameters, outer diameters, wall thicknesses, and lengths. Custom manufacturing services are available for specialized geometries, tapered structures, multi-bore designs, and precision-machined quartz components according to customer drawings and technical requirements.<\/p>\n

Whether for prototype development, laboratory research, or volume production, our high-purity quartz capillaries provide reliable performance and consistent quality.<\/p>\n
