Ultra Aromax Columns (USP L11), Particle Size 5 μm, Length 250 mm, ID 4.6 mm, Restek (CAT#: STEM-C-0902-LC)

The Ultra Aromax Columns (USP L11) manufactured by Restek are made of high-purity, type-B silica that minimizes activity and creates high-density bonding. These columns are ideal for selective and reliable HPLC applications.
Ultra Aromax Columns (USP L11) is a unique reversed-phase material that exhibits extreme retention and selectivity for aromatic and/or unsaturated compounds. This column is ideal for applications where increased retention is required, and it's a suitable choice for gradient LC-MS analyses when conventional columns are not giving adequate retention or selectivity.
