Yarra™ is a family of aqueous size-exclusion chromatography (SEC) columns for biomolecule analysis. Yarra columns are engineered to provide efficiency increases of up to 70% and higher resolving power. Yarra columns, offered in three phases with 3-micron particles, are designed for the separation of small to large proteins and peptides, as well as biological therapeutics and biosimilars. Their hydrophilic surface chemistry promotes high resolution and minimal absorption of proteins for accurate quantitation.
