The Ultra line represents Restek’,s broadest selection of stationary phases on a single silica support. Made of high-purity, type-B silica that minimizes activity and creates high-density bonding, these columns are designed for selective and reliable HPLC applications.

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.
