Ultra Silica HPLC Prep Column, 5 µm, 50 x 21.2 mm

• Easy scale-up from Restek analytical columns.
• Popular bonded phases.

Restek makes it easy to scale up your separations. We offer a wide range of semipreparative and preparative-scale columns packed with many of our popular Ultra, Allure, Pinnacle DB, and Viva bonded phases on a 5 ?m spherical silica. Other stationary phases are also available—please call and inquire.

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

Features & Benefits

Our broadest selection of stationary phases, including unique phases. High-density bondings for maximum retention. High-purity, Type-B silica gives excellent peak shapes for a wide range of compounds.

Note: We strongly recommend ordering a semi-prep or prep column only after evaluating the desired separation on an equivalent analytical-scale column. Because we cannot reuse a column or the silica it contains once it has left our facility, we cannot accept returns of large-scale columns.
