Creating Solutions Where Chemistry and Biology Meet

At SACHEM, we have harnessed over 50 years of expertise in providing high purity, precision chemical solutions and combined it with innovative displacement chromatography technology to create a portfolio of enabling displacers called Expell™, Propell™,  and Isolis™ for use in protein and oligonucleotide purification and impurity isolation. 

Expell™: Cation, anion, HIC and reverse phase displacers for use in Protein Purification via displacement chromatography

Propell™: Anion and reverse phase displacers for use in oligonucleotide purification via displacement chromatography

Isolis™: Cation, anion and reverse phase displacers for use in impurity isolation via displacement chromatography

These displacers are designed and manufactured with high purity and precision.  They operate on the molecular level in order to solve your most challenging processing issues and support the most demanding applications.
