Pre-owned chromatography columns for protein and nucleic acid purification. Affinity, size exclusion, ion exchange, and more - sourced from research labs worldwide.
FPLC columns are among the most expensive consumables in biochemistry research. New Cytiva/GE columns can cost thousands of dollars - but well-maintained used columns perform just as well at a significantly lower price.
SIB SCI sources pre-owned chromatography columns directly from research labs, universities, and biotech companies. Each column is inspected and tested before listing. We carry affinity, size exclusion, ion exchange, and other column types from Cytiva (GE Healthcare), Bio-Rad, Tosoh, and other major manufacturers.
Highest selectivity purification. Captures target proteins directly from crude lysate with minimal steps. Essential for His-tag, GST, and antibody purification.
Separates proteins by molecular size. Used for polishing steps, buffer exchange, and studying protein complexes. Critical for final-stage purity.
Separates proteins by surface charge. Anion and cation exchange columns widely used for intermediate purification steps in multi-step protocols.
Separates proteins based on surface hydrophobicity under high-salt conditions. Used as a polishing step after ion exchange or affinity chromatography.
Combines multiple interaction modes for enhanced selectivity. Useful for difficult separations and when traditional single-mode columns are insufficient.
Rapid removal of salts, small molecules, or detergents from protein samples. HiTrap Desalting and PD-10 columns for fast sample preparation.
