UV stop quartz tube：
1.specification is OD14mm*WT1.1mm*Length1240mm
2.hydroxy content:＜25
3.widely used in quartz halogen lamps,high density discgarge lamps and other UV light
4.efficient,healthy,no harm to health,no pollution,economic,long life
5.it can adjust to temperature of space automatically
6. UV stop glass tube is doped Ce，can stop nearly all the radiation of ultraviolet ray of UV-B,UV-C and all of ultraviolet ray of UVA,it is the ideal material of the most spectral transmission
7.dinmension tolerance
