Category: CF to Glass Adapter Kovar

Open End Kovar Glass Adapters for CF Vacuum flanges serve as practical solutions for affixing glass accessories to metal high vacuum systems or connecting flange-mounted components to glass systems.

The invention of Kovar was driven by the necessity for a dependable glass-to-metal seal, essential in electronic devices like light bulbs, vacuum tubes, cathode ray tubes, as well as in vacuum systems utilized in chemistry and various scientific research fields.

Comprising an iron-nickel-cobalt alloy, Kovar boasts a coefficient of thermal expansion akin to that of hard (borosilicate) glass, ensuring compatibility and reliability in diverse applications.
