Description
A thin, semi-permeable film that allows small molecules, such as water, solvents and ions, to pass while preventing larger molecules. Membrane filters usually have a pore size of 8 - 100 angstroms. They are usually made from either natural materials or synthetic polymers such as cellophane, collodion, or asbestos fiber. Membrane filters are used for desalination, electrolysis procedures, gas separation and metal extraction.
