Cellulose Nitrate Membrane, Plain, Sterile, 0.45um Pore Size, 47mm Circle (100 pcs) SKU: 10401170

Cellulose Nitrate (CN) Membrane Filters - 10401170

Engineered for high retention efficiency and superior chemical stability, the Whatman 10401170 achieves reliable separation results across a broad range of analytical and preparative applications. Manufactured to exacting specifications, a uniform Cellulose Nitrate (CN) matrix maintains its rated 0.45 cutoff under the pressures and flow conditions encountered during routine laboratory filtration. Accordingly, consistent surface properties across the full membrane area support uniform particle capture and reliable results in gravimetric, microscopic, and culture-based analytical workflows.

Material Specifications

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.
Autoclavable at 121°C without loss of integrity, cellulose nitrate membranes maintain their rated pore structure and dimensional stability through repeated sterilization cycles.
Surface retention characteristics allow captured particles and microorganisms to remain on the membrane face, supporting direct microscopic examination and physical recovery of collected material.
Dissolves completely in specific organic solvents, enabling full recovery of captured particles from the membrane surface for downstream gravimetric, chemical, or spectroscopic analysis.

Reporting filtration parameters alongside your analytical results demands documented pore size, material chemistry, and lot traceability — the membrane specifications above provide the specificity that reviewers and auditors expect. Specifically, 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. Make the decision for consistency and reliability, ensuring that your laboratory maintains its reputation for high-quality, error-free output.
