With more than 35 years of professional know-how in HPLC Restek is one of the most important producers of liquid chromatography columns. The company develops high-quality HPLC and GC columns as well as suitable HPLC accessories. The Restek HPLC columns are available in different phases such as Allure, Pinnacle DB, Pinnacle II, Raptor, Ultra or Viva. You can also choose between various packing specifications, lengths and particle sizes. Use the menu on the left or our HPLC column configurator to compare HPLC columns from Restek with the other manufacturers such as Agilent, Waters or Thermo Fisher.

Pinnacle DB columns are 100% manufactured by Restek in the Bellefonte, Pennsylvania, facility. Because performance begins with the support, Pinnacle® DB UHPLC columns start with base-deactivated spherical silica that is optimized for UHPLC stability. From there, Restek bonds them with a wide variety of phases to give chromatographers a stable and selective column. These columns combine selectivity and efficiency for UHPLC columns.

Viva columns are based on a wide-pore material Restek designed for optimal large- molecule separations. In developing Viva silica, Restek found that although many commercial wide-pore silicas meet the standard 300 Å mean pore size, most have very broad distributions about this mean with a signiicant portion of their pore volume falling below 150 Å. This means a large portion of the surface area is unavailable to larger molecules. Viva columns have a narrow distribution around the mean pore size, permitting a larger portion of the silica surface to play a role in the separation.
