TSKgel Ether-5PW

TSKgel Ether-5PW is based on a 100 nm pore size polymethacrylate base material bonded with polyether groups.  The TSKgel Ether-5PW column is stable in either acid or caustic cleaning regimens and provides excellent access to larger molecules with low diffusion coefficients.

TSKgel Ether-5PW is less hydrophobic than Phenyl-5PW and the best choice for the separation of very hydrophobic proteins or monoclonal antibodies.
