Diol Series

Develosil Diol Series Product Brochure

The Develosil 100 Diol and 300 Diol was designed for gel filtration using Develosil’s high quality Si gel. This column is used worldwide in food research specifically with proanthocyanidins.

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.
