Pinnacle DB IBD UHPLC Column from Restek

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