I. Application
Water treatment and other sterilization fields.
II. Product Features
A kind of transparent quartz glass material with high purity, high temperature and corrosion resistance, high thermal stability and mechanical properties, and a special treatment process for high transmittance (typically over 60%) in the ultraviolet region (185 nm). Strict dimensional tolerance and excellent appearance make the bulb have good shape.
III. Product Type
WQPQ182，High Ozone transparent quartz tube
