Pinnacle - II HPLC Prep 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, Pinnacle® II, and Viva bonded phases on a 5μm spherical silica. Other stationary phases and particle sizes are also available—if you need a phase on 7μm, 10μm or 15μm particles, please call.

Please 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 re-use a column or the silica it contains once it has left our facility, we cannot accept returns of large-scale columns (except in cases of our error).
