Cosmotec Isolator

Isolator Our Isolator is a ceramic joint which provides ideal electrical isolation from the vacuum chamber.  Our Isolators are offered in voltages from 6 to 24kV DC and the inner diameters from 5 to 135mm.  In addition to these standard Isolators, we also offer Isolators with welded bellows that provide vibrational absorption and alignment for applications where the Isolator is intended to be used between rigid components. We offer Isolators in alternative types of flanges including NW / KF, ConFlat®, ISO-K, ISO-F and ASA elsewhere on our site. Don't forget we can also manufacture custom components for you on a rapid turnaround schedule — contact us for more details.
