transparent Quarzrohr

Transparent quartz tube Transparent quartz glass tube is the industry standard with a transparent fused quartz glass, silica is greater than 99.9% purity, good stability, corrosion resistance, spectral transmittance of the high price was cheap. Mainly used in electric light source industry, and some for the semiconductor, optical and chemical industries.
