Ultra Silica, 3 µm, 100 x 4.6 mm HPLC Column

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.

Base-deactivated spherical silica is useful for normal-phase or HILIC separations.
