Description

Ozone free quartz tubeis used for making "Ozone free " UV sterilizing lamp. it is transparent, cut surface is slight purple.doped with Ti , can prevent radiation of high-density UV rays but generate no ozone. Spectrum transmission at **5 nm is 0 and no ozone generated . UV transmission at **4 nm is more than *0%. the UV sterilizing lamps made by electric melting quartz tube have much longer life than fused quartz tube.
