Restek HPLC Columns - Pinnacle DB
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 eiciency for UHPLC columns.

Restek HPLC Columns - Viva
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.
