The Kurt J. Lesker Company was founded in 1954 as a manufacturers' representative for vacuum products in Pittsburgh PA, USA. Today, we are an international manufacturer and distributor of vacuum components and vacuum systems for research and industrial applications. We have three manufacturing locations, two in Pittsburgh and one in the UK; sales offices and warehouses across North America; KJLC offices in England and Hungary; and a network of agents around the world.

We believe we are still the only company offering a free service that answers technical questions from anyone in the vacuum community. Our popular Tech Info service receives thousands of questions regarding almost every aspect of vacuum science. Our technical specialists respond promptly to all questions associated with vacuum practice, vacuum technology, and thin film deposition, even if those questions come from our competitors.
