Capillary Silica Quartz Rod

Capillary silica quartz rod is a slender, high-purity cylindrical component made from fused silica (quartz), characterized by its ultra-fine diameter, exceptional chemical inertness, and thermal stability (withstanding up to 1650°C). Designed for precision applications requiring minimal fluid or gas resistance, it is widely used in analytical instruments (e.g., gas chromatography), microfluidic systems, capillary electrophoresis, and optical fiber fabrication, where its smooth surface, dimensional precision, and ability to withstand high temperatures or corrosive environments ensure reliable performance in delicate scientific and industrial processes.
