Diol Series
The Develosil 100 Diol and 300 Diol was designed for gel filtration using
Other typical uses for this column is size exclusion chromatography of large water-soluble compounds such as proteins and enzymes.
For low molecular compounds, we recommend the 100 Diol; and for large macromolecular compounds, we recommend the 300 Diol.
