Product Detail
vacuum tube made of high borosilicate 3.3 glass and has an all glass double-tube co-axial structure.

vacuum tube

The evacuated tubes are made in high quality boronsilicon glass  It can endure 0,6Mpa pressure and the hail which is smaller than 25mm The absorption is boosted by a Nitrogen and Aluminum solution sputtered in the space between the two pipes. The rate of absorbingis more than 0,92.The tubes exist  different diameters: Φ47, Φ58,Φ70 -800mm, 1200mm, 1500mm, 1600mm,1800mm, 1900mm, 2000mm, 2100mm.The rate of vacuum between the pipes is below 5*10-3Pa which is the best rate currently available for evacuated tubes. The average pressure in the market is 5*10-2P
