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 PK Series ODS 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.
