Dialysis is a physical separation method in which small molecules pass through the pores of a selective membrane while larger molecules are retained in the dialysis chamber.

The Harvard Apparatus dialyzer portfolio is a family of products for the dialysis of small sample volumes of proteins, peptides, nucleic acids, and other biomolecules. We offer products suited for ultra-micro volumes as little as 1 µl to larger volumes up to 10 ml, and a range of reusable, disposable, and equilibrium dialyzers.
