Three target purple *7mm *8mm vacuum tube
Â
Three target vacuum tube is made of high borosilicate glass 3.3,which could resist hail resistance of steel ball(Φ*0mm) from the height of **0mm.
Â
The evacuated process of all vacuum tubes last more than 3 hours in order to ensure the perfect vacuum degree,thus, the insulation will be fully guaranteed.
Â
This vacuum tube adopts sputtering technology (SS-ALNx/Cu),which could not only make sure the high absorptivity ,but the lifespan of coating layer could reach to *5 years or even longer.Â
