Restek Ultra C1 5um 100 X 4.6mm

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.

This exceptionally stable C1 phase features our least-retentive reversed-phase hydrocarbon packing.
