TRANSPARENT TUBE

The transparent quartz tube is obtained through different types of raw materials that include natural or synthetic quartz sand. Quartz tube have ultra high purity, good spectral transmission, well controlled dimensions and lower (OH) Hydroxyl.

Some of the other properties include

  • These are highly resistant to thermal shock due to extremely low co-efficient of thermal expansion
  • They have excellent electrical strength that offer stability under temperature variation

They are available from 2mm inside diameter to 200mm outside diameter up to 3000mm length.
