Each product group contains columns with distinctly different pore sizes, and one mixed-bed column.

TSKgel PW columns are composed of spherical, hydrophilic polymethacrylate beads. Particle sizes range from 12 µm for the smaller pore size columns to 17 µm for the larger pore size columns. TSKgel G2500PW is ideally suited for the analysis of water-soluble polymers with molecular weights of less than 3,000 Da.

Product Attributes: Base material: hydroxylated polymethacrylate Particle size (mean): 12 and 17 μm Pore size: < 200 Å Calibration range:  up to 3000 Da (polyethylene  glycols & oxides) Max. % organic:  20% Shipping solvent: water
