In biologics purification, bead strength and accessibility often compete: more crosslinking adds rigidity but tightens pores for large molecules. NanoPak-B embeds low-loading graphite microparticles inside a hydrophilic polymer microbead. The graphite reinforces the structure, while the polymer remains the chromatography-facing surface for ligand chemistry. See how this composite design, with micron-scale through-pores, balances strength, accessibility, and gentle surface che
