Square Quartz Capillary Tube
Micro quartz glass capillary tubes and rods are made of high purity silicon dioxide in thermal processing method. The tubes and rods are drawn at one time, dimension and tolerance are uniform which in high precision, good tolerance control.
The Main Properties of Quartz Glass:
* Mechanical properties
Quartz glass is a brittle material with low tensile strength and high compressive strength. The latter is 20 times that of the former.
* Thermal performance
Quartz glass has a very low coefficient of linear expansion, very good resistance to thermal vibration, and is a poor conductor of heat.
* Optical performance
An important difference between quartz glass and ordinary glass is its good transmittance in the entire spectrum, especially in the ultraviolet and deep ultraviolet spectrum, which is not available in ordinary optical glass.
* Electrical performance
The main electrical properties of quartz glass are high dielectric electric field strength, low dielectric loss and low conductivity.
* Chemical properties
Quartz glass is a material with very good chemical stability and does not react with water, salt solutions and most acids.
* Radiation resistance
Compared with ordinary glass, quartz glass has excellent radiation resistance. Among them, synthetic quartz glass has the best radiation resistance and hardly produces color centers.
The unique characteristics of quartz capillary tubes and rods make it the material of choice for many analytical techniques, including gas and liquid chromatography, capillary electrophoresis, DNA sequencing and fragment analysis genomics, proteomics, microfluidics, controlled supply of gases and fluids, andhigh-precision flow cell for blood cell counting. In the optical communication industry, quartz capillary tubes can also be used as key components of optical fiber pigtails, optical fiber sleeves, fiber optical couplers, etc.
The hydroxyl groupfor water (OH content) in the quartz glass is a harmful impurity in the quartz glass. It can reduce the high-temperature viscosity of the quartz glass, thereby reducing the temperature resistance. When the quartz glass is used as an optical element, the hydroxyl group will change a series of physical parameters such as the refractive index, light transmittance, and thermal expansion coefficient, hence affecting the crystallization performance of quartz glass. We can produce low OH content capillary tubes and rods, which is used in many applications.
