Ultra HPLC Columns
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.
Exceptionally stable C4 packing with high bonding coverage and base deactivation.
Less retention than C18 or C8 phases.
