Membrane discs are thin, precut circular membranes used for filtration and separation processes across various industries. They consist of microporous polymeric or inorganic materials designed to retain particles, microorganisms, or contaminants larger than their defined pore size, primarily by surface capture. These discs provide efficient and reliable filtration solutions for both liquid and gas samples, ensuring high process reliability and reproducible results in scientific, medical, and industrial applications.

Key Features

• Available in a wide range of membrane materials such as nylon, cellulose nitrate, polyethersulfone (PES), polypropylene, and PTFE, each offering different chemical compatibility and hydrophilic or hydrophobic properties.

• Uniform pore size distribution and thickness for consistent filtration performance.

• Manufactured under strict quality control ensuring integrity and sterility; many discs can be gamma sterilized

• Available in multiple diameters and thicknesses to fit various filter holders and systems.

• Some membranes offer special properties like hydrophobicity or oleophobicity for venting or pressure compensation applications.

• Resistant to chemicals and compatible with aggressive solutions depending on membrane type.

Applications

• Sterile filtration and bioburden reduction in aqueous and non-aqueous solutions.

• Filtration of pharmaceuticals, food and beverage products, and biological samples.

• Water treatment including wash water, purified water, and water for injection (WFI).

• Gas venting and pressure compensation in industrial packaging and components.

• Microbiological analysis, laboratory sample preparation, and environmental monitoring.

• Filtration in semiconductor and electronics manufacturing for ultra-pure water and chemical solutions.
