GraviPur™6 Desalting Column with G-25 Medium Size Exclusion Resin for cleanup of 6 mL sample
Desalting Columns prepacked with G-25 Medium size-exclusion chromatography dextran resin for rapid cleanup of 6 mL samples. Ready for gravity, vacuum, pump applications ... Read more
Description
GraviPur™ Desalting Columns are prepacked with PROTEINDEX™ SEC G-25 Cross-linked Dextran Resin, a molecular-weight–based selection resin designed for rapid and efficient removal of small molecules. With an effective cutoff of approximately Mr 5,000, these columns enable biomolecules larger than the exclusion limit—such as proteins, peptides, nucleic acids, and other macromolecules—to be cleanly separated from salts, detergents, and other low–molecular-weight contaminants.
Optimized for convenience and reliability, GraviPur™ column body is made of bio-compatible polypropylene (PP), and the frits are hydrophilic, enabling fast flow through driven by gravity. A stopcock was provided with each column for better flow control during operation. The integrated Luer-lock outlet provides secure, direct connection to female Luer ports on standard vacuum manifolds. When used with the optional adapter (Cat# 21-0336, designed for 1/8" O.D. tubing, sold separately), the column can also be operated with peristaltic pumps or medium-pressure automated systems, offering enhanced versatility for different workflows.
With their high sample-loading capacity and ready-to-use design, GraviPur™ Desalting Columns deliver a cost-effective, reliable, and easy-to-integrate solution for buffer exchange, desalting, and sample cleanup, ideal for routine laboratory applications or seamless incorporation into existing purification systems.
