Thumbnail Filmstrip of Cellulose Nitrate Membrane Circle, Plain, 0.2um Pore Size, 90mm, 25/Pk Images
Cellulose Nitrate (CN) Membrane Filters - 7182-009
Precision-manufactured Hydrophilic membrane with a verified 0.2 pore structure delivers consistent retention performance across demanding laboratory filtration workflows. A uniform Cellulose Nitrate (CN) matrix maintains its rated 0.2 cutoff under the pressures and flow conditions encountered during routine laboratory filtration. Precision manufacturing ensures that each membrane disc delivers the rated retention, flow rate, and surface consistency that analytical and microbiological methods require.
Material Specifications
- Dissolves completely in specific organic solvents, enabling full recovery of captured particles from the membrane surface for downstream gravimetric, chemical, or spectroscopic analysis.
- Naturally hydrophilic and compatible with aqueous solutions, cellulose nitrate delivers high flow rates and rapid wet-out without requiring pre-conditioning or surfactant treatment.
- High protein binding capacity makes cellulose nitrate the preferred membrane for Western blotting, dot blotting, and nucleic acid immobilization techniques that rely on efficient surface adsorption.
- Surface retention characteristics allow captured particles and microorganisms to remain on the membrane face, supporting direct microscopic examination and physical recovery of collected material.
- Economical bulk packaging supports laboratories with high consumable throughput where individual sterile wrapping is unnecessary.
Multi-site studies where different laboratories must produce comparable data benefit from membranes manufactured to tight specifications, giving you confidence that site-to-site variability is not introduced by the filtration step. In practice, the narrow pore size distribution of cellulose nitrate membranes ensures your retention data is consistent across batches, reducing the inter-sample variability that complicates quantitative particulate and microbiological analyses. Secure your research outcomes by partnering with a filtration solution that understands your need for speed, accuracy, and reproducibility.
