Size Exclusion Chromatography Resin NRPB133, 1000~5000 (CAT#: STEM-AL2-0918-ZJF)

This product is a chromatography medium intended for size-based biomolecule separation. It is configured as a solid-phase separation medium. Separation is based on the pore structure of the matrix rather than on a specific affinity ligand. The medium is intended for packed-bed chromatography under the conditions stated in the source data. The source data define the applicable flow, pH, and pressure conditions for the supplied configuration. Chemical compatibility information supports equilibration, washing, regeneration, and cleaning workflows where applicable. Storage conditions are specified to maintain the medium before use and between operations. The product can be integrated into laboratory or process purification workflows consistent with its stated separation mechanism.
