Product Description

High efficiency heat focus vacuum tube is made by the newest nanotechnology ,its absorb floor is made from copper, stainless steel and aluminium by the *2 -floor spatter plating technology. High boron silicon glass is chosen. By the gradually ss-c/cu selective complex coat, the vacuum tube have the high absorptance and low reflectance. The vacuum tube have the heat preservation effect because of its vacuum interlayer and its temperature can be up to **0oC,especially the superconduct heat tube.
