• Q: Why quartz tubes break after only used for several times?

    A: Quartz tubes can be long-term used under 1100℃. However, if the temperature is too high, but the hours of use don’t decrease, the quartz tubes will break due to the unbearable heat.

     If the chamber door be opened right after the experiment, quartz tubes will break because of the temperature drop dramatically.

    Moreover, quartz tubes get contaminated by gasifying coating materials in the chamber. After a long time, quartz tubes will break due to the impurities.
