Application
Germicidal lamp, Medium pressure mercury lamps for germicidal, water treatment and other UV-C lamps sleeve
Product Feature
A clear quartz glass tube doped with titanium, it can prevent heavy UV radiation and produce no ozone.It has extremely low OH levels and precise dimensional tolerances to ensure the lamp's long life.
It is made of fused quartz in special industrial technology glass, which is a very good base material.Quartz glass has a series of excellent physical and chemical properties.
The feature of the clear quartz glass is as follows: high purity, strong transmission, strict size control, low OH content and so on. OH content can be controlled less than 20ppm\15ppm\10ppm\5ppm\2ppm.
Product Type
PQ221，Standard Ozone Free Quartz Tube
