Pinnacle DB columns are 100% manufactured by Restek in our Bellefonte, Pennsylvania facility. Because performance begins with the support, our Pinnacle^® DB UHPLC columns start with base-deactivated spherical silica that is optimized for UHPLC stability. From there, we bond them with a wide variety of phases to give chromatographers a stable and selective column. Get the most out of your UHPLC system. Combine selectivity and efficiency by using Restek Pinnacle^® DB UHPLC columns
