Membrane filters are thin, porous materials designed for laboratory filtration applications. They consist of a semi-permeable membrane made of materials such as cellulose acetate, polyethersulfone (PES), nylon, or polytetrafluoroethylene (PTFE). Membrane filters are available in various pore sizes, allowing for precise particle retention and separation of substances based on size.

Membrane filters are commonly used in laboratories to remove particles, microorganisms, or impurities from liquids or gases. They provide a barrier that allows the passage of the desired substance while blocking or retaining unwanted particles. The selection of the appropriate membrane filter depends on factors such as the particle size to be retained, the nature of the sample, and the required flow rate.
