High-Performance Size Exclusion Chromatography for Rapid Desalting and Buffer Exchange
FPLC Purification, Size Exclusion – ZetaSep and ZetaPrep Columns for Rapid Removal of Salts and Small Molecules
emp BIOTECH’s ZetaSep and ZetaPrep columns are engineered for fast, reproducible size exclusion chromatography using FPLC and other LC systems. Packed with Zetadex-25 Superfine resin, they efficiently separate biomolecules from low-molecular-weight contaminants like salts, dyes, and solvents. These columns are ideal for proteins, oligonucleotides, and other macromolecules larger than 5 kDa and are available in multiple formats to suit different flow rates and sample volumes.
