Differentially Pumped Viewports

Specifically designed for extreme high vacuum applications such as geochronology, LewVac’s differentially pumped windows employ all-metal, dual seals, having a port that accesses the resulting cavity between the seals. The port can be attached to an auxiliary pump to extend the vacuum range beyond UHV.
This design has become the standard for geologists studying argon & helium dating.
