AE99/5 8.0um 50mm 100/Pk HYRIM SKU: 10405079

Cellulose Nitrate (CN) Membrane Filters - 10405079

Designed to deliver reproducibility and confidence across critical sample types, the Whatman 10405079 provides the filtration consistency that method validation demands. Building on this foundation, precision membrane geometry balances retention sharpness with sustainable flow rates, minimizing the pressure buildup that leads to premature filter replacement. With this in mind, controlled production conditions produce membranes with documented pore size distribution and thickness tolerances, supporting method reproducibility across multiple filter lots.

Material Specifications

• Bulk format reduces per-unit packaging waste and cost, appropriate for routine particulate removal and clarification where aseptic handling is not specified.
• Naturally hydrophilic and compatible with aqueous solutions, cellulose nitrate delivers high flow rates and rapid wet-out without requiring pre-conditioning or surfactant treatment.
• 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.
• Cellulose nitrate membranes feature a narrow pore size distribution and low extractable levels, providing the controlled retention characteristics required for gravimetric and particulate analysis.

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. Here, 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. Secure your research outcomes by partnering with a filtration solution that understands your need for speed, accuracy, and reproducibility.

• Microscopy Examination - Particles remain on the membrane surface for direct visual inspection, supporting identification and classification.
• Biochemical Assays - High protein-binding capacity effectively immobilizes macromolecules, supporting lateral flow and diagnostic testing.
• 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.
• Aerosol Analysis - Low tare weight and acid digestibility enable chemical characterization of airborne particulates from air sampling.
• Environmental Compliance - Documented retention characteristics at standard pore ratings support reproducibility in regulated testing programs.
