TSKgel PWXL SEC Column Series, 7-13 µm (CAT#: STEM-BC-3241-ZJF)

This high-performance size-exclusion column series is designed for water-soluble polymers. It uses highly hydrophilic vinyl-polymer-based packing. All analytical columns use the common 7.8 mm internal-diameter by 30 cm format. Five primary pore-range grades cover different molecular-weight distributions. Columns of different ranges may be connected in series for broad polymer analysis. Particle sizes range from 7 to 13 µm depending on the grade. Molecular-weight exclusion limits extend from 5 × 10³ to at least 2.5 × 10⁶ for the specified models. The series supports food, chemical, pharmaceutical, and biopharmaceutical polymer characterization.
