Advantages:

It is know to all，that among the mercury arc spectrum for lamps only the Ultraviolet at 253．7nm is strong enough to kill bacteria．The quartz glass tubes for the UV sterilizing lamps produced in our company，their transmissivity at 253．7nm is over 70％， have high reputation in the lamp factories of China． Now there is a question noticeable，in our country all the mercury lamps transmit 185nm short wave ultraviolet rays， which result in ozone，the ozone in the air even With a ]ow tensity(for example o.1ppm) can irritate person to have mucosa，headache even coma， and pollute the air seriously． To solve this problem our company has developed new ozone free transparent quarts glass tubes with excellent transmissivity at 253．7nm and transmissivity cut at short wave UV 220nm．The sterilizing lamps made of this tubes have a strong sterilizing ability， and no ozone produced．They are the best environmental protectled product5±Or the people．

Technique standard of ozone froe transparent quartz glass tube

Physics and chemistry properteis，outside，test，check and accept accord with the Ministry standard JC／T598-1995;

Spectrum property(sample thickness 11．2mm)：

a．Visible rays transmissivity in average>88％；
b．Transmission of the UV cut wave 220nm≤4％：
C．TransmiSSion Of the special wavelength 253．7nm for sterilizing lamp>70%；
d．Ozone and sterilized result in sterilizing lamps made of these tubes accord with the medical ministry standard．
