ENrich size exclusion chromatography columns are designed for high-resolution separation of proteins and other biomolecules at fast flow rates.

These chromatography columns contain polymeric resin to separate biomolecules by their size.

ENrich size exclusion columns are available in two particle sizes:

• ENrich SEC 70 10 x 300 mm column (780-1070) — for separating biomolecules in the 500 Da to 70 kDa range
• ENrich SEC 650 10 x 300 mm column (780-1650) — for separating biomolecules in the 5 to 650 kDa range
• Both ENrich columns operate at a maximum pressure of 600 psi

Features and Benefits of ENrich Size Exclusion Chromatography Columns

• Flexible flow rate with different sample viscosities and temperature conditions
• Superior quality, reproducible separations
• Faster flow rates than similar media
• Stable from pH 2 to 12

Applications of ENrich Size Exclusion Chromatography Columns

For purifying biomolecules in a variety of workflows:

• High-resolution separation of biomolecules
• Contaminant removal
• Molecular size analysis
• Purity determination

These size exclusion columns are compatible with organic acids (1 M acetic acid), 8 M urea, 6 M guanidine HCl, chaotropic agents, detergents, salts, and 1 M NaOH. Alcohol, up to 20% v/v, can be used to enhance the solubility of nucleotides and peptides.

This support is completely compatible with all commonly used aqueous buffers.
