MDC Precision offers a complete line of vacuum breaks, also known as electrical isolators, for demanding ultra-high vacuum (UHV) applications and environments. Composed of metal adapters brazed to each end of an insulating ceramic tube that provides voltage isolation between the conductive metal ends, vacuum breaks provide an electrical break between the vacuum chamber and other external components, as well as electrostatic discharge (ESD) protection of sensitive components in the vacuum system. 

Constructed using high-purity alumina ceramic insulators hermetically bonded to low-expansion metal Kovar® sleeve adapters, the electrical breaks are attached to other vacuum components such as flanges, bellows, chambers and weldables using MDC’s proprietary UHV brazing techniques. All materials and braze alloys used are vacuum grade and chosen for their specific characteristics and ability to maintain the integrity of the seals for use in demanding applications and environments. A maximum thermal gradient of 25°C per minute must be observed to preserve the life of the seal. Weldable vacuum breaks are typically installed using one of the following fusing processes: laser, electron-beam or TIG welding.
