Membrane Filters are precision laboratory filtration tools used for the separation, purification, and analysis of liquids and gases. They are thin, microporous sheets made from specialized polymers or cellulose derivatives, designed to retain particles, microorganisms, or molecules above a specific pore size while allowing the solvent or smaller molecules to pass through. Membrane filters are widely used in pharmaceuticals, microbiology, biotechnology, food & beverage testing, and environmental monitoring.

• High Filtration Precision: Available in pore sizes ranging from 0.1 µm to 10 µm, with 0.22 µm and 0.45 µm being common for microbiological and sterile filtration.

• Material Options:

  • Cellulose Nitrate (CN): High flow rate, commonly used in microbiology.

  • Cellulose Acetate (CA): Low protein binding, ideal for biological samples.

  • Polyethersulfone (PES): Fast flow, chemically resistant.

  • Polytetrafluoroethylene (PTFE): Hydrophobic, suitable for air/gas and aggressive solvents.

  • Nylon & PVDF: Broad chemical compatibility, suitable for aqueous & organic solvents.
