Glass capillary tubes are made borosilicate glass and quartz glass,it is used widely in Optical fiber and communication industry,Medical, laboratory,biochemical, chemical, organic, analytical and other thin layer point.etc,We can offer micro diameter 0.1mm glass capillary tube.
Advantages of quartz glass:
1, high temperature resistance, quartz glass softening point temperature 1730 degrees Celsius, can be used at 1100 degrees Celsius for a long time, can be used at 1450 degrees Celsius for a short time.
2, corrosion resistance, in addition to hydrofluoric acid, quartz glass almost does not react with other acid substances, its acid resistance is 30 times that of ceramic, 150 times that of stainless steel, especially at high temperature, chemical stability is incomparable to any other engineering materials.
3, good thermal stability, the thermal expansion coefficient of quartz glass is very small, can withstand drastic temperature changes, the quartz glass heated to 1100 degrees Celsius, into the room temperature water will not crack.
4, good transmittance performance, quartz glass in the ultraviolet to infrared spectrum band has better transmittance performance, visible light transmittance is greater than 93%, in the ultraviolet spectrum region, the maximum transmittance can reach more than 80.
5, good electrical insulation performance, quartz glass resistance value is equivalent to ordinary glass ten thousand times, is an excellent electrical insulation material, even at high temperature also has good electrical properties.
