Half Round Optical Quartz Glass Tube

Quartz tube or fused silica tube is glass tube consisting of silica in amorphous (non-crystalline) form. It differs from traditional glasse tube in containing no other ingredients, which are typically added to glass to lower the melt temperature. Quartz tube, therefore, has high working and melting temperatures. The optical and thermal properties of quartz tube are superior to those of other types of glass tube due to its purity. For these reasons, it finds use in situations such as semiconductor fabrication and laboratory equipment. It has betterultraviolet transmission than most other glasses.

quartz tube

1)High purity :SiO2> 99.99%.
2)Operating Temperature: 1200℃; Soften Temperature: 1650℃ .
3)Excellent visual and chemical performance:acid-resistance,alkali resistance,Good thermal stability
4)Health care and environmental protection.
5)No air bubble and no air line.
6)Excellent electrical insulator.

We supply all kinds quartz tube:Clear quartz tube,Opaque quartz tube,UV blocking quartz tube ,Frosty quartz tube and so on.

If the quantity you need is large, we can customize some special size quartz tube for you.
OEM is also accepted.

Attention for quartz tube 

1. Do not operate in temperature beyond quartz maximum working temperature for long time. Otherwise, products will deform                      crystallization or become softening.
2. Clean the quartz products before high temperature environment operation .
Firstly soak the products in 10% hydrofluoric acid, then wash it with high purity water or alcohol .
Operator should wear thin gloves , direct touch with the quartz glass by hand is inhibited.
3. It is wise to extend the lifespan and thermal resistance of quartz products via continuous use within high     temperature                           environment. Otherwise, interval use shall shorten products lifespan.
4. Try to avoid touch with alkaline substances (such as water glass, asbestos, potassium and sodium             compounds, etc.)when          employing quartz glass products in high temperature, which is made of 
acid material.

     Otherwise product anti- crystalline properties will be greatly reduced.
