C18 Phases: SP-ODS-PK

At DAISOGEL, we recognized the need for a premier silica gel that resolves complex impurities of modern recombinant peptide therapeutics in a sustainable, cost-effective manner.

A silica gel robust enough to withstand the rigors of alkaline CIP. A silica gel whose mechanical strength would preclude the generation of fines and hence sustain consistent operating pressures during large-scale purification in DAC columns. And a silica gel whose loading capability simply outperforms other similar medias on the market, providing the best economics for large scale peptide purification.


Typical Applications

Premium ODS for Recombinant Peptides + Insulin

Small Molecules

Synthetic Peptides

Recombinant Peptides / Insulin

High Sensitivity

The ODS-PK Series has been developed based on our holistic design concept of chemical stability, mechanical strength, and high performance to provide you with the ultimate in sustainable purity. Its 18% carbon loading strikes the right balance that is ideal for the purification of fibrillating peptides.
