High purity Capillary Quartz Tubes (or Quartz/Glass Capillary Tubes) with its optical, physical, mechanical, electrical, and other outstanding features, are widely used in optical fiber and communication industry such as PLC Splitter, Wavelength Division Multiplexer (WDM), Fiber Optic Sensor (FOS), Optical Fiber Communication Systems and other optical fiber transmission facilities. Quartz Capillary Tubing is the essential component and required material of the Gas Chromatographs, High Performance Capillary Electrophoresis Chromatograph (HPCE), High Performance Liquid Chromatograph (HPLC) and Micro fluidics instruments in Electronic, Medical Treatment, and Optical industry.
