Ultra II® HPLC Prep Columns



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, Ultra II, 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.


High density bondings, for maximum retention. Restek manufactured, high-purity, type B silica gives excellent peak shapes for a wide range of compounds.

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).
     
We accept Visa, MasterCard and American Express   
Buy from an Authorized Restek Distributor to ensure top product quality, full warranty protection, and reliable technical support.
