Ultra C18 HPLC Prep Column, 5 µm, 250 x 10 mm
Overview
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.
- 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 μm spherical silica. Other stationary phases are also available—please call and inquire. The general-purpose Restek C18 is a conventional monomeric octadecylsilane column suitable for analyses of a wide range of compounds from acidic through slightly basic.
