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.

Note: We strongly recommend that you only order a semi-preparative or preparative column once you have evaluated the desired separation on an equivalent column on an analytical scale.
Because we cannot reuse a column or the silica within it once it leaves our facility, we cannot accept returns of large columns.
