Microfiber Filters

Membrane filters and microfiber filters support laboratory sample preparation, microbiological testing, particle retention and controlled filtration workflows. John Morris Group supplies nitrocellulose, cellulose nitrate and cellulose acetate filter options in common diameters and pore sizes through the Laboratory range, with Labfriend category access for laboratory procurement teams.

Australian laboratories can select filter formats for sterile filtration, microbiological analysis, environmental testing, sample clarification, quality control and routine analytical preparation. Established in 1952 and ISO 9001 certified, John Morris Group supports consumable selection, bulk purchasing and technical product matching through factory-trained engineers on 1300 501 555.

Membrane Filters And Microfiber Filters For Laboratory Filtration

Microfiber filters in this category are product-led around laboratory membrane filtration, including nitrocellulose, cellulose nitrate and cellulose acetate filters. Visible options include 25 mm, 47 mm and 50 mm formats, 0.2 µm, 0.20 µm, 0.45 µm and 0.80 µm pore sizes, plus sterile, non-sterile, white, black and gridded versions for different analytical workflows.

How To Choose The Right Laboratory Filter

• Pore size: Select 0.2 µm or 0.20 µm filters for finer particle retention or microbiological workflows, and 0.45 µm filters for many routine membrane filtration and sample preparation tasks.
• Filter diameter: Match 25 mm, 47 mm or 50 mm filters to the holder, manifold or filtration device used in the laboratory.
• Membrane material: Choose nitrocellulose, cellulose nitrate or cellulose acetate based on chemical compatibility, flow performance, protein binding, sample type and method requirements.
• Sterility and colour: Use sterile formats where contamination control is required, and black or gridded membranes where colony visibility or counting support is important.
• Pack requirements: Review pack quantities and stocking needs where filters are used in routine, high-volume or multi-site testing workflows.

Applications Across Laboratory And Environmental Testing

These filters support workflows across Laboratory, Environmental, Life Science and Diagnostics, water testing, microbiology, quality control and research environments. They are commonly used for particle capture, microbiological testing, sample clarification, sterile filtration and preparation before downstream analysis.

Related Filtration Categories

For complete filtration workflows, membrane and microfiber filters can be sourced alongside Laboratory filter papers, Laboratory filtration hardware or accessories, Syringe filters and Industrial filtering and purification. These related categories help laboratories match filter media, holders, prefilters and disposable filtration products to the method.
