Kurt J. Lesker Company

The Kurt J. Lesker Company, founded in 1954, is a global manufacturer of vacuum components and complete systems for high vacuum and UHV applications. The company offers more than 14,000 vacuum equipment products from warehouses throughout North America and Europe and has more than 200 employees worldwide. Our Website has full E-commerce capabilities. In addition to standard vacuum flanges, components, feedthroughs, vacuum fluids, and gaskets, we engineer and manufacture magnetron sputtering sources for R&D and large-scale production applications, a wide range of pure materials, custom chambers, and evaporation sources (including organics). Since 1980 our Process Equipment Division has manufactured complete sputter deposition, e-beam and thermal evaporation, molecular beam epitaxy, and laser ablation systems. They range from laboratory bell jar units to fully automated large-scale production systems, with the present emphasis on organic thin-film deposition systems for OLED and PLED flat panel displays and combinatory materials research. Our distributor relationships with major vacuum pump manufacturers enable us to sell a wide variety of coarse pumps; rotary vane and piston pumps; roots pumps; dry piston, scroll, screw, and diaphragm pumps; turbo, drag, and hybrid pumps; diffusion pumps; and ion pumps—often from our stock. Our skilled Vacuum Services group repairs and rebuilds all models of mechanical, diffusion, and turbo-pumps, and reclaims expensive vacuum fluids.
