HPLC Column, Nanofilm SEC-250, 250 Å, 5 µm, 7.8 x 150 mm

Utilizing proprietary surface technologies, Nanofilm® SEC phases are made of the uniform, hydrophilic, neutral, and polymeric thin films chemically bonded on the high purity and enhanced mechanical stability silica. Nanofilm® SEC phases have been innovatively and specially designed to ensure high resolution and maximum recovery for the separation of biological molecules at low salt concentration or organic buffers. The narrow dispersed, spherical silica particles of the Nanofilm® packings for SEC-150, SEC-250, and SEC-500 have nominal pore sizes at 150, 250, and 450 Å, respectively.
