Prep Columns

Ultra Aqueous C18 HPLC Prep Columns

More Details
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.
