Founded in 1985, we are a leading developer and manufacturer of chromatography columns, sample preparation and collection products, reference standards, and instrument accessories. We work with analysts around the world, providing them with tools to monitor the quality of air, water, soil, foods, botanicals, pharmaceuticals, and chemical and petroleum products.

We are passionate about our science and about making innovative products that enable great chromatography. We are also just as committed to providing exceptional customer service that exceeds your expectations. Our founder called it “Plus 1” service, which is a term you will still hear us use today, and it helps us fulfill our mission to be your first and best choice for chromatography.

Restek is a 100% employee-owned company with a long history and strong corporate culture. We are independent, and that means we are not bound to a specific brand of instrument. Whether your chromatograph is a time-tested workhorse or your newest investment, we are ready to help you get the most out it. We serve everyone equally, and we appreciate your loyalty every time you choose Restek.

Located in offices around the globe, we believe our unique perspectives strengthen our organization, but some things are the same no matter where you live or how you choose to engage with Restek. We pride ourselves on delivering the best customer experience to every analyst we work with. Wherever you are, we are ready to build a long-lasting partnership with you and your lab, through top-quality products backed by expert education and superior technical service.

Our customers’ work makes the world a safer and healthier place, and we are excited and grateful for the chance to help you make a difference. Contact your local Restek office or distributor today to learn how.
