AE99 8.0um 50mm 100/Pk SKU: 10400114

Cellulose Nitrate (CN) Membrane Filters - 10400114

Designed to deliver reproducibility and confidence across critical sample types, the Whatman 10400114 provides the filtration consistency that method validation demands. Complementing this, a uniform Cellulose Nitrate (CN) matrix maintains its rated 8.0 cutoff under the pressures and flow conditions encountered during routine laboratory filtration. On this basis, from raw polymer through final inspection, the manufacturing process is designed to ensure that every membrane disc meets the performance specifications of its grade designation.

Material Specifications

• Cellulose nitrate membranes feature a narrow pore size distribution and low extractable levels, providing the controlled retention characteristics required for gravimetric and particulate 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.
• Bulk packaging format provides cost-effective access for high-volume laboratories performing non-critical filtration and sample preparation.
• 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.

Maintaining accreditation under ISO 17025 or similar quality frameworks requires documented traceability at every step — the specification compliance of each membrane lot supports your ongoing audit readiness. 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. Elevate the quality of your analytical data today by standardizing on a filtration product built to meet the exact specifications of your applications.

• Microscopy Examination - Particles remain on the membrane surface for direct visual inspection, supporting identification and classification.
• Water Quality Testing - Narrow pore distribution retains indicator organisms consistently for regulatory compliance in environmental laboratories.
• Routine Sample Prep - Uniform microporous matrix provides consistent flow rates and reliable particle retention for general aqueous solutions.
• Biochemical Assays - High protein-binding capacity effectively immobilizes macromolecules, supporting lateral flow and diagnostic testing.
• Colony Enumeration - Gridded surface variants facilitate accurate plate counting of captured microorganisms under standard magnification.
• Aerosol Analysis - Low tare weight and acid digestibility enable chemical characterization of airborne particulates from air sampling.
