      Restek Ultra, Viva, Allure

      The Ultra line represents Restek’s broadest selection of stationary phases. Comprised of high-purity, type-B silica, Ultra columns are designed for reliable HPLC applications and are scalable to prep.

      Viva columns have a 300Å pore size with a narrow distribution to allow maximum interaction and retention of larger molecules.  Viva is designed for protein and peptide separations and available in 6 phases.  

      Allure columns have a 60Å pore size and a high surface area, making them the most retentive of all Restek brands.   Two specialty phases are available for Organic Acids and Aldehydes and Ketones (AK.)
