UV stopping quartz tubes /UV blocking Quartz tubing for UV lamps by GE214 material

It can almost prevent all the UV rays
This cerium-added quartz tube can effectively prevent all radiation of UV-B and UV-C ultraviolet and most radiation of UV-A ultraviolet .It is the best materials to prevent UV with best transparent performance. It can be used to make quartz halogen lamp , gas discharge lamp and other UV lamp-house , which will effectively protect human and object from hurt of ultraviolet and maintain the best efficiency of light transmission.
