Quartz Capillary Tubes (All Special Types)

MachinedQuartz manufactures a range of specialty quartz capillary tubes including rectangular cross-sections, D-shape profiles, and outer-square inner-round configurations. These custom geometries are used in advanced microfluidics, specialty optical waveguide, and scientific instrumentation applications where standard circular or square tubes are not suitable. All special types can be fabricated to custom dimensions and lengths. Contact us for a quote with worldwide shipping.
