Product Feature：
It is a doped transparent quartz tube, which is about 150 ° C lower than conventional quartz glass materials. The extreme tolerance size control makes it have superior processing performance. It can be used in high-speed fast processing lines. It also has low hydroxyl group and UV-filter. C UV and other properties
