NC45 0.45um 110mm 50/Pk SKU: 10401126

Cellulose Nitrate (CN) Membrane Filters - 10401126

Engineered for high retention efficiency and superior chemical stability, the Whatman 10401126 achieves reliable separation results across a broad range of analytical and preparative applications. At its core, precision membrane geometry balances retention sharpness with sustainable flow rates, minimizing the pressure buildup that leads to premature filter replacement. 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

• Surface retention characteristics allow captured particles and microorganisms to remain on the membrane face, supporting direct microscopic examination and physical recovery of collected material.
• 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.
• Bulk packaging format provides cost-effective access for high-volume laboratories performing non-critical filtration and sample preparation.
• Dissolves completely in specific organic solvents, enabling full recovery of captured particles from the membrane surface for downstream gravimetric, chemical, or spectroscopic analysis.

Whether your method calls for gravimetric analysis, particle visualization, or microbial enumeration, the pore consistency and surface uniformity documented above ensure that your results reflect the sample — not the filter. Cellulose nitrate's dimensional stability through autoclaving at 121°C means your membranes maintain their rated pore structure and physical dimensions from pre-sterilization through final analysis, supporting method reproducibility. Make the decision for consistency and reliability, ensuring that your laboratory maintains its reputation for high-quality, error-free output.
