Quartz Tube can be transparent or milky white. These quartz tubes can withstand up to 1100 degree centigrade. It is most important to note that Quartz Tubes can withstand very high thermal shock (1000 degree centigrade to room temperature).
The transparent quartz tube is obtained through different types of raw materials because that includes natural or synthetic quartz sand. These are highly resistant to thermal shock due to the extremely low coefficient of thermal expansion because they have excellent electrical strength that offers stability under temperature variation.
antsLAB™ Quartz Tubes can withstand vacuum up to 10−3 Torr.
