The High Rejection Solvent Recovery Membrane is a high rejection spiral-wound nanofiltration membrane for continuous solvent recovery and extract concentration in botanical extraction systems. It selectively permeates solvent molecules while retaining cannabinoids, terpenes, and other valuable extract components, enabling efficient solvent reclamation without evaporation. Compatible with Infinity Filter nanofiltration systems; the high rejection variant is optimized forhigh solute rejection applications requiring maximum extract concentration.
