Filter Medium

Gel filtration chromatography, also known as size-exclusion chromatography or molecular sieve chromatography, achieves separation and purification based on the varying elution rates of molecules of different sizes within the column.
The dextran gel has good stability, commonly used in desalting or buffer exchange. In general, gels with higher degree of cross-linking and smaller pores are suitable for separating bioproducts of low molecular weight, while gels with lower degree of cross-linking and larger pores are suitable forseparating bioproducts of high molecular weight.
