Robust Performance in Space Applications

In the vacuum of space, volatiles from construction materials condense on optics and electronics, degrading their performance or causing failures.

Sealtron and Hermetic Seal outgas space grade connectors in a hard vacuum for 24 hours, eliminating the volatiles from the connector.

Testing of the outgassed elastomeric materials to ASTM E-595 revealed levels of Total Mass Loss of less than 1.0%, Collected Volatile Condensable Materials of less than 0.1%, and Water Vapor Recovered of less than 1%.

Hermetic Seal & Sealtron vacuum furnaces can achieve a maximum operating temperature of 1343°C (2450°F) at 5x10-6 torr vacuum, suitable for your special processes
