RC Membrane (RC55), 0.45um Pore Size, 100mm Circle (25 pcs) SKU: 10410219

Regenerated Cellulose (RC) Membrane Filters - 10410219

Designed to deliver reproducibility and confidence across critical sample types, the Whatman 10410219 provides the filtration consistency that method validation demands. Optimized for laboratory use, precision-manufactured Hydrophilic membrane with a verified 0.45 pore structure delivers consistent retention across the full operating range. To this end, precision manufacturing ensures that each membrane disc delivers the rated retention, flow rate, and surface consistency that analytical and microbiological methods require.

Material Specifications

• Symmetric pore geometry provides predictable retention behavior across varying flow rates and pressure conditions.
• Resistant to a wide range of organic solvents including alcohols, ethers, and hydrocarbons that degrade cellulose-based alternatives.
• Minimal extractable levels make Regenerated Cellulose a reliable choice for analytical applications where background interference must be minimized.
• A premium choice for broad chemical compatibility without requiring pre-wetting.
• Regenerated Cellulose offers excellent chemical resistance to both aqueous and organic solvents.

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. In response, low binding combined with high flow rate makes RC particularly effective when you need to filter dilute biological samples where both recovery and throughput matter to your results. Secure your research outcomes by partnering with a filtration solution that understands your need for speed, accuracy, and reproducibility.

Hydrophilic

• Dialysis Membrane Sheet - Used in custom dialyzers to facilitate buffer exchange and desalting of protein solutions via passive diffusion.
• Particle Sizing - Used in automated particle counters to provide a clean, non-shedding background for accurate contaminant sizing data.
• Tissue Extract Clarification - Handles lipid-rich tissue extracts well, preventing the premature fouling often seen with hydrophobic membrane types.
• Multiplex Bead Assays - Retains microspheres in flow-through assays while allowing the sample matrix to wash away without trapping the beads.
• Organic Solvent Cleaning - Compatible with DMSO and other harsh organics, making it perfect for combinational chemistry sample clarification.
• Microplastic Collection - Filters water samples to capture microplastic fibers, providing a smooth background for microscopic categorization.
