Restek History


Restek opened for business in 1985, occupying a single room in a converted elementary school in Pennsylvania, United States. Our founder and only staff member at the time, Paul Silvis, had a vision for the future: to create a place where people looked forward to coming to work as much as they looked forward to going home. With that foundation, we quickly grew into a global company with locations coast to coast in the U.S. as well as in China, France, Germany, Italy, Japan, Spain, and the United Kingdom.

Product & Applications Development

Innovative, reliable products and robust applications to support them are essential, but so is being able to consistently provide them year after year. Restek has a strong tradition of accelerated growth and technological advancement, and we are set up to continue this trend far into the future—presenting you with a stable, long-term source for innovative new products and support for getting the most out of them in your lab.

Manufacturing Capabilities

Restek began as a manufacturer of GC columns, but to ensure our future independence, we expanded our in-house manufacturing over the years to cover all of our product lines. More recently, we also acquired MicroQuartz GmbH, to supply our own fused silica for our GC columns, and Glastron, Inc., to ensure a consistent and steady stream of GC inlet liners no matter how high the demand or complex the geometry.

Proven Stability

Since 1985, we have weathered every national and global financial crisis without losing our ability to serve the chromatography community with essential products or technical service. While no one knows what the future holds, our continued growth, a strong foundational culture, and our unwavering commitment to taking care of each other and our customers means that Restek will be a solid partner for years to come.
