Ultra Silica 3µm and 5µm Columns (USP L3)
By Restek
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.
