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 — applied upstream in Nanostar Sieving®, and downstream in Tangential Flow Filtration, post-conjugation purification, and in-process solvent recycling.
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 — today spanning synthesis, purification and solvent recovery, with new applications in active development.
