Chromalite 5AD1 is a non-functionalized, highly crosslinked, low porosity polymer.  Available in small, uniform particle sizes, Chromalite 5AD1 is ideal for reverse-phase high pressure liquid chromatography (RP-HPLC). The spherical beads show exceptional batch-to-batch consistency, enabling simple scale-up from laboratory analyses through to full-scale plant operation.

Packed into columns, sizes includes:

10.0mm x 150mm
10.0mmx 250 mm
21.2mm x 50mm
21.2mm x 100mm
