Filter Membrane Nylon, 0.22 µm & 0.45 µm Pack of 200

Description

The Filter Membrane Nylon, 0.22 µm & 0.45 µm, also known as nylon membrane filter discs, polyamide membrane filters or laboratory microfiltration membranes, is designed for separating suspended particles from compatible liquid samples during laboratory filtration procedures. Manufactured from nylon (polyamide), these membrane filters feature a naturally hydrophilic surface that allows aqueous liquids to pass through without requiring additional wetting agents. Nylon also provides mechanical strength and chemical resistance for routine laboratory filtration applications.

The range includes two nominal pore sizes, 0.22 µm and 0.45 µm, with both variations featuring a 47 mm membrane diameter. These options allow laboratories to select the appropriate membrane according to particle retention requirements, sample characteristics and analytical methods. The 0.22 µm Nylon Membrane Filter is suitable for fine filtration applications requiring removal of smaller suspended particles. It may also be used in selected microbial retention procedures, although sterilising-grade performance must be confirmed and validated for the specific membrane and application. The 0.45 µm Nylon Membrane Filter is commonly used for routine liquid clarification, particulate removal and sample preparation. Its larger nominal pore size generally allows higher flow rates than a comparable 0.22 µm membrane under similar operating conditions. The 47 mm circular membrane design is suitable for compatible laboratory vacuum filtration systems, membrane filter holders and filtration funnels. Correct installation and sealing help prevent liquid bypass during filtration.

These nylon membranes are useful for HPLC mobile phase preparation, solvent filtration, aqueous sample clarification and analytical laboratory testing. The selected pore size should match the filtration requirements of the sample and subsequent analytical procedure. Nylon membranes can exhibit relatively high non-specific protein binding, making them less suitable for applications where maximum protein recovery is required. Alternative low-protein-binding membranes may be preferable for sensitive biological samples. For filtration, place the membrane into a clean, compatible 47 mm holder using appropriate forceps. Secure the filtration assembly and apply the required vacuum or pressure within the manufacturer’s specified operating limits.

Safety Precautions: Confirm chemical compatibility before filtering solvents or concentrated chemicals. Avoid damaging the membrane surface during installation. Sterility, temperature limits and pressure ratings should be verified before specialised filtration procedures. Each selected variation is supplied as one pack of 200 Nylon Membrane Filters, available in either 0.22 µm or 0.45 µm pore size. Filtration funnels, holders, vacuum pumps and other accessories are not included unless specified separately.
