Gel Filtration Column

Bio-Rad has a range of gel filtration columns optimized for a wide array of uses — for fractionation within a size range and group separation. Size range fractionation is useful for purifying biomolecules with different sizes but similar physicochemical properties (charge, polarity, hydrophobicity, etc.), such as native proteins. Group separation is generally used to remove salts and other small molecules from a solution of large molecules, such as proteins or other polymers.
