Repack Kits for LC Columns

MODcol® Spring® Repack Kits are designed to ensure efficient, reproducible repacking of preparative LC and SFC columns across multiple internal diameters. Each kit contains precisely matched components and frits, enabling reliable bed formation, consistent flow distribution, and extended column lifetime.

Available for 25, 50, 70, and 101 mm ID Spring Columns, the repack kits support different frit porosities—including standard and double-density frit designs—to meet varying performance and pressure requirements in LC and SFC applications.
