Gel Filtration Chromatography Media
Cellufine™ GCL-2000/Cellufine™ GCL-2000HF

Gel Filtration, or size exclusion chromatography, has proven to be a simple and effective purification method for proteins and other biomolecules. However, the traditionally slow flow rates and limiting resolving power of most gel filtration media have restricted its usefulness. These problems, inherent to the packings, existed not only at the laboratory preparative scale but especially at process scale. The limited throughput of gel filtration columns has often created a significant process bottleneck.
Cellufine GCL media overcome these limitations. The mechanical strength of the spherical cellulose matrix allows high flow rates, even in large industrial columns.
