Thumbnail Filmstrip of Plain Cellulose Nitrate Membrane, 0.1um Pore Size, 50mm Circle (100 pcs) Images
Cellulose Nitrate (CN) Membrane Filters - 10402014
The Whatman 10402014 combines a controlled pore size distribution with low extractable levels, ensuring the data accuracy that sensitive analytical methods require. Engineered for demanding applications, verified 0.1 pore distribution across the Hydrophilic membrane surface guarantees batch-to-batch consistency in particle capture and analyte passage. On this basis, each membrane disc reflects a manufacturing standard where retention characteristics, physical integrity, and dimensional accuracy are verified before release.
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.
- Cellulose nitrate membranes feature a narrow pore size distribution and low extractable levels, providing the controlled retention characteristics required for gravimetric and particulate analysis.
- 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.
- Packaged without sterilization for applications where downstream sterility is achieved by other means or is not a process requirement.
Air monitoring and stack emissions sampling demand a filter medium that withstands the thermal and chemical conditions at your collection point — the material properties described above define the operating envelope for your application. For this application, low extractable levels in cellulose nitrate membranes mean your blank measurements stay minimal, giving you the confidence that weight changes in gravimetric analysis reflect actual sample content rather than membrane artifacts. Elevate the quality of your analytical data today by standardizing on a filtration product built to meet the exact specifications of your applications.
