Wahl Separations develops and licenses a novel class of highly porous and solvent selective polymer filters which provide orders of magnitude better performance than currently available media. These polymers can be cast into sheets, for simple membranes, or columns for use in chromatography. The polymers also can be 3D printed in a way to allow one to separate some miscible solvents (e.g. H2O & isopropanol) by filtration instead of distillation.
