emp BIOTECH ZetaSep FPLC Desalting Columns

ZetaSep FPLC desalting columns efficiently separate large biomolecules like proteins and nucleic acids from small impurities such as salts, dyes, and other contaminants, while enabling buffer exchange. These columns offer simple, rapid, and reproducible separation, ideal for post-purification desalting or buffer exchange. They handle sample sizes of 200 µL (1 mL column) and 1 mL (5 mL column), effectively removing low-molecular-weight impurities from biomolecules larger than 5 kDa. Featuring Zetadex-25 Superfine, a high-flow, chemically stable size-exclusion matrix, ZetaSep desalting columns provide excellent resolution with minimal buffer and pH effects.
