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 low density (for example 0.1ppm) 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 quartz glass tubes with excellent transmissivity at 253.7nm and transmissivity cut at short wave UV220nm. The sterilizing lamps made of this tubes have a strong sterilizing ability and no ozone produced. They are the best environmental protection products for the people.The UV sterilizing lamps (include ozone-free la

High-temperature-proof, wear-and tear-proof, acid-and alk ali-proof,clarity and being able let the ultraviolet and ultra red rays go through ,are its significant characteristics.The fusing crystal is consisted by the original granules under high temperature that exceeds 1800. The content of crystal (whose molecular formula is SiO2)reaches as high as over 99.7%.So it is fabric crystal material of high purity,which will never deform and blast after extremely cold and hot. The meat roasted by cooker made by it, with a kind of special flavor, tastes much more delicious , thus, it will increase your appetite. Because of its high hardness level and clarity, the plate is easy to clean and food won't stick on it. Crystal plate for roasting is a kind of environmental, fashionable and green present of high quality. We stick to the principle of providing superior quality and favorable price to satisfy the customers, needs. We sincerely welcome clients of all walks both at home and abroad.
