Aluminum Chambers
Atlas Aluminum vacuum chambers have excellent ultra high vacuum (UHV) properties: Aluminum has 10,000,000x (7 orders of magnitude) less Hydrogen permeation than stainless steel. Consequently, aluminum chambers have far less H2, H2O, & hydrocarbon vapor at high vacuum and ultra high vacuum levels.
