Advanced Membrane Technology

Precision-engineered membranes for exact polymer manufacturing

Exactmer is a provider of disruptive technology for exact polymer synthesis in liquid phase. The foundation of our innovation is our proprietary range of Organic Solvent Nanofiltration (OSN) membranes. These highly selective membranes can be applied to both upstream, in the Nanostar Sieving platform for API synthesis and solvent recycling, and in downstream process Tangential Flow Filtration (TFF).

The Core Platform

One membrane technology. Many ways to apply it.

Our advanced membrane capabilities enable the production of membranes with unparalleled stability in organic solvents, and high permeance, selectivity and durability. From our Advanced Membrane Manufacturing Suite in Dagenham, we produce a range of membranes tailored to the needs of specific applications.
