 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.

    within high temperature environment. Otherwise, interval use shall shorten products lifespan.
