TSKgel Octadecyl-2PW

TSKgel Octadecyl-2PW is based on a highly cross-linked polymethacrylate base matrix bonded with octadecyl groups. The polymeric matrix provides excellent stability in high pH buffer systems and can withstand rigorous cleaning with either acid or base. The 12.5 nm (125 Å) pore size of TSKgel Octadecyl-2PW columns makes them ideally suited for peptides and small proteins. They demonstrate faster analysis than other competitive reversed phase polymeric columns.
