Kurt J. Lesker Company


As a leading global provider of high-quality vacuum products and systems, along with an established tradition of service and attention to detail, the Kurt J. Lesker Company® (KJLC®) has built a reputation for being “All Things Vacuum.”

The common attribute across the entire company is the relentless and tireless pursuit of quality and customer satisfaction, both in the vacuum products and the services we provide worldwide. KJLC® takes this responsibility seriously, working at all levels to ensure high quality performance in all our products.

Thin-Film Vacuum Deposition Systems:

We manufactured our first thin-film vacuum deposition system over 20 years ago at our U.S. headquarters in Pittsburgh, Pa. Hundreds of systems later our proven Process Equipment Division, with engineering, manufacturing, and clean-room assembly areas in the U.S. and U.K., design and manufacture PVD and CVD deposition systems to suit your process application needs.

And we now offer three different computer-controlled atomic layer deposition (ALD) system platforms to support varying levels of R&D; from compact, stand-alone ALD systems, to fully-integrated multi-technique deposition cluster tools — we have the right platform to support your level of research.

We can develop simple single-chamber bell jar systems for smaller R & D applications to complex multi-chamber computer-controlled cluster tool systems for OLED/PLED production, and everything in-between. Our systems can include a variety of deposition techniques, including magnetron sputtering (RF, DC, and Pulsed DC) sources in both linear and circular configurations, ion sources for substrate cleaning and assisted deposition, electron beam evaporation, thermal evaporation for metals and organics, and pulsed laser ablation.

We also offer our materials customers sputter target bonding and precious metals reclamation services, saving you both time and money.


Traps & Filters: Protecting the vacuum chamber from vapors produced by the pumps; protecting the pumps from gases and particulates originating in the chamber; and protecting people and the atmosphere from materials from both pumps and chamber, is the job of a trap, filters, or abatement system. We offer a full range of components including:

Foreline traps; System traps; Mist eliminators, Oil Filtration units, and complete Exhaust Gas Abatement systems.

Vacuum Fluids & Greases: For almost 40 years we have manufactured hydrocarbon vacuum pump fluids of all grades and viscosities. Our semi-synthetic hydrocarbon vacuum pump oil offers superior chemical stability. KJLC’s new line of semi-synthetic mechanical pump oils offers superior performance. KJLSS oil contains an anti-oxidation additive which extends the useful life of the oil. With its low vapor pressure this oil is an ideal choice for a variety of applications. KJLSS is a semi-synthetic oil with a high viscosity index, which makes it much more energy efficient than many other vacuum pump oils. It has the added benefit of being able to withstand higher operating temperatures. This new oil is available in four different types, with varying viscosities.
