As the interest for membrane-based organic solvent separation increases, membrane materials exhibiting high permeance, high selectivity, and long-term stability against solvents are sought. Membrane technology has experienced tremendous progress by integrating well-established polymeric membranes with emergi Popular Advances
Aug 7, 2018 · DO USE: for filtering solvents and other aggressive chemicals, such as acetone and DMSO. MAYBE USE: when you need to filter aqueous solutions and sodium hydroxide. You’ll need to pre-wet with a water-miscible solvent, such as methanol, to overcome the hydrophobicity of the membrane. Polyvinylidene Fluoride (PVDF) Membrane
Feb 22, 2017 · Organic solvent nanofiltration. Unlike traditional aqueous nanofiltration membranes, which are usually used to separate charged ions and other compounds from water, organic solvent nanofiltration
Jul 30, 2019 · Membranes with high solvent permeance and excellent molecular sieving characteristics are highly desirable for energy-efficient organic liquid separation. However, the “trade-off” relationship between permeability and solute selectivity remains a challenge for thin film composite (TFC) polymeric membranes.
GH Polypro (GHP) Membrane Disc Filters Membrane with Chemical Compatibility for Aqueous Solutions and Aggressive Solvents Maximum versatility. Filters aqueous solutions or aggressive chemicals. Low protein binding membrane gives high recovery of critical proteinaceous samples. HPLC certified.
Apr 23, 2021 · Organic membranes are those made of petroleum-based synthetic polymers, including polysulfone (PS), polyethersulfone (PES), and polyvinylidene fluoride (PVDF), while inorganic membranes include ceramics, carbon molecular sieves, zeolites, amorphous silica, among others. A majority of industrial membranes consist of synthetic or natural polymers.
