- 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.
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.
Particle Size: 5 µm, spherical
Pore Size: 100 Å
Carbon Load: 20%
pH Range: 2.5 to 8
Temperature Limit: 80°C
USP Phase Code: L1
Phase Category: C18, octadecylsilane
Ligand Type: monomeric C18
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 reuse a column or the silica it contains once it has left our facility, we cannot accept returns of large-scale columns.
