Borosilicate Glass

Corning 7056 - Borosilicate Glass / Viewports

Accu-Glass Products' Glass Vacuum Viewport Flanges are designed for all general purpose uses such as the direct observation of processes in a vacuum chamber.  The glass used in the vacuum viewport is Corning Type 7056 glass (a Borosilicate Glass), which is the most common material used for vacuum viewports.  Accu-Glass Products' glass viewports are designed for both high and ultrahigh (UHV) vacuum applications, using the latest in glass-to-metal bonding technology to seal the 7056 glass to the stainless steel or nickel-iron alloy sleeves.

Since glass is susceptible to scratching and weak under point stresses, caution must be exercised when handling viewports to minimize the chance of implosion hazard.
