Cellulose Nitrate Membrane Circle, Plain, 0.2um, 50mm, 100/Pk SKU: 10401314

Cellulose Nitrate (CN) Membrane Filters - 10401314

The Whatman 10401314 protects sensitive instrumentation and sample integrity by providing reliable particulate removal with minimal analyte adsorption or background interference. From a technical standpoint, precision membrane geometry balances retention sharpness with sustainable flow rates, minimizing the pressure buildup that leads to premature filter replacement. Taken together, 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

• Economical bulk packaging supports laboratories with high consumable throughput where individual sterile wrapping is unnecessary.
• Autoclavable at 121°C without loss of integrity, cellulose nitrate membranes maintain their rated pore structure and dimensional stability through repeated sterilization cycles.
• Dissolves completely in specific organic solvents, enabling full recovery of captured particles from the membrane surface for downstream gravimetric, chemical, or spectroscopic 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.
• Surface retention characteristics allow captured particles and microorganisms to remain on the membrane face, supporting direct microscopic examination and physical recovery of collected material.

Multi-site studies where different laboratories must produce comparable data benefit from membranes manufactured to tight specifications, giving you confidence that site-to-site variability is not introduced by the filtration step. To meet this need, 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.

• Bioburden Monitoring - Surface retention keeps captured organisms accessible for direct incubation and enumeration without transfer steps.
• Water Quality Testing - Narrow pore distribution retains indicator organisms consistently for regulatory compliance in environmental laboratories.
• Aerosol Analysis - Low tare weight and acid digestibility enable chemical characterization of airborne particulates from air sampling.
• Biochemical Assays - High protein-binding capacity effectively immobilizes macromolecules, supporting lateral flow and diagnostic testing.
• Microscopy Examination - Particles remain on the membrane surface for direct visual inspection, supporting identification and classification.
• Colony Enumeration - Gridded surface variants facilitate accurate plate counting of captured microorganisms under standard magnification.
