Lesker Tech Archives


Lesker Tech Banner

Lesker Tech was a PDF vacuum technology newsletter offered by KJLC covering all aspects of vacuum. Past topics have included improving base pressure in chambers, pumping speed and throughput, gas flow, overview of basic vacuum concepts, chamber bakeout, types of chamber heaters, and more.

Lesker Tech has since evolved into KJLC Innovate. With this transition we're opening our Lesker Tech Archives to the public. Click on a back issue to load it as an Adobe PDF file which may then be viewed, saved, or printed.
