WCN WH 25mm 3.0um 100/Pk SKU: 7193-002

Cellulose Nitrate (CN) Membrane Filters - 7193-002

Precision-manufactured Hydrophilic membrane with a verified 3.0 pore structure delivers consistent retention performance across demanding laboratory filtration workflows. Verified 3.0 pore distribution across the Hydrophilic membrane surface guarantees batch-to-batch consistency in particle capture and analyte passage. 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

• 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.
• Dissolves completely in specific organic solvents, enabling full recovery of captured particles from the membrane surface for downstream gravimetric, chemical, or spectroscopic analysis.
• Supplied in bulk non-sterile packaging, offering an economical option for routine clarification and general laboratory filtration tasks.
• Naturally hydrophilic and compatible with aqueous solutions, cellulose nitrate delivers high flow rates and rapid wet-out without requiring pre-conditioning or surfactant treatment.

If your protocol requires direct on-membrane analysis by microscopy or culture, the surface characteristics and dimensional tolerances described above give you a substrate that performs consistently from disc to disc. Because cellulose nitrate dissolves completely in organic solvents like acetone and amyl acetate, you can recover every captured particle from the membrane surface for downstream gravimetric, spectroscopic, or chemical analysis. Make the decision for consistency and reliability, ensuring that your laboratory maintains its reputation for high-quality, error-free output.

• Microscopy Examination - Particles remain on the membrane surface for direct visual inspection, supporting identification and classification.
• Environmental Compliance - Documented retention characteristics at standard pore ratings support reproducibility in regulated testing programs.
• Gravimetric Particulate Analysis - Dissolves in organic solvents for complete particle recovery and accurate weight-based quantification.
• Bioburden Monitoring - Surface retention keeps captured organisms accessible for direct incubation and enumeration without transfer steps.
• Routine Sample Prep - Uniform microporous matrix provides consistent flow rates and reliable particle retention for general aqueous solutions.
• Aerosol Analysis - Low tare weight and acid digestibility enable chemical characterization of airborne particulates from air sampling.
