Deep Cutoff Ozone Free Quartz Tube

I. Application

Mainly used for Tanning lamps.

II. Product Features

It is a kind of clear quartz glass tube doped with titanium. Different from PQ221, it can absorb all the UV-C, which protect against harmful ultraviolet radiation.The extremely low OH (OH less than 1ppm) prolongs the lamp’s life.

III. Product Type
