About glass tube：

Glass tubes are made of soda-lime, borosilicate or quartz material and they have broad range of quality. Glass tubes are widely used in laboratory, chemical industry, biology industry, gardening, and so on.

According to different dimension and accuracy, glass tubes can be divided into normal glass tube, precision glass tube and heavy wall capillary tube three kinds.

With good chemical, mechanical and thermal properties, small tolerance and various dimension, the glass tubes are widely used in daily life, industry and laboratory.

Quartz glass tube are engineered to optimize performance or economy for specific applications. Our quartz tubes are available in clear fused quartz glass as well as fused silica.

Our company produce a wide range of dimensions for applications such as general lighting, laser flash lamps, digital projection, semiconductor (lithography/cleaning), and UV curing. Materials are available as standard stock items or custom fabrication with precision accuracy.

Besides lamp applications, VY could provide you with precision glass tube and glass rod for medical, electronic, and optical communications, as well as scientific applications. We have different grade of material choice for you, which could meet your vaerious demands, whether performance or economy.

Properties of Quartz Glass:

– Extreme wide spectral transmission range from deep UV to middle IR.
– High optical transmission and low optical absorption.
– Low variation and disturbance of the refractive index in one solid piece and optical homogeneity from one melt to the next.
– High resistance to high intensity laser radiation, which also applies to the UV spectral range (e.g. excimer laser).
– High application temperature 1200 degrees C — almost four times higher than ordinary glass.
– Low thermal expansion coefficient resulting in an extremely high temperature shock resistance allowing rapid heating & cooling.

People also ask

• What is the purpose of the glass tube?
  Laboratory glass tubingis used in many laboratories or industrial workplaces to connect other items of glassware or equipment and to convey or deliver chemicals, solvents, liquids, gases and other products.
• How Strong is Quartz Tube?
  The material is extremely strong in compression, with design compressive strength of better than 1.1 x 10 9 Pa (160,000 psi). Surface flaws can drastically reduce the inherent strength of any glass, so tensile properties are greatly influenced by these defects
