| Specifications︰ | Transparent quartz tube is made of high purity crystal sand . It was pulled out from high temperature melting furnace.
(similar to GE214, GE219, SG25 )
The surface of this kind of tube is smooth and the tube is colorless. The properties of the tube are: high purity(SiO2>99.99% ); abrasion resistance(except hydrofluoric acid & hot phasphoric acid); fire resistance(softening point 1700 centigrade); low coefficient of thermal expansion(5.5x10-7/centigrade, heat the tube to around 1100 centigrade, then put it into ordinary temperature water, the tube won't crack); transmission of light (penetration efficiency of visible radiation over 93%), transmit ultraviolet; excerllent insulating property; long usable life, no contamination. It is widely used in heating, lighting, electronics, semiconductor, optical fiber field and so on.
