Product Description

What is the “molecular level high-vacuum violet gold tube ”?

The “molecular level high-vacuum violet gold tube ” is the solar tube produced by the process of multi-target&high frequency magnetron sputtering continuous coating and vacuumized by the high-vacuum compound molecular pump.

a).The vacuum degree of molecular-level violet gold tube reaches 10-4pa, which is one degree higher than other vacuum tubes in this industry and two degree higher than the national standard.

b).It‘s heat preservation performance is 10 times of the common vacuum tubes.

c). It has realized the permanent high vacuum degree in the real sense.

d).The annual output of automatic production line of molecular level high-vacuum violet gold tube is 20 million.

e).Whole glass vacuum tubes adopt the material of USA borax,TURKEY boric acid,low iron high purity refined quartz sand and etc.

f).Type of the vacuum tube: High borosilicate glass3.3/molecular level high-vacuum violet gold tube.
