Light Guide Quartz Glass Square Rods Quartz Glass Square Rods Stirring Glass Rods
Product Description:
The standard transparent quartz tube is made of high-purity quartz sand. High purity, strong heat resistance, high light transmittance and accurate size.
Quartz rods are used to manufacture high temperature and corrosion resistance of semiconductors, electric light sources, semiconductor communication devices, lasers, optical instruments, laboratory instruments, electrical
equipment, medical equipment and chemical instruments, chemical industry, electronics, metallurgy, building materials and national
defense industry. It is widely used.
