RC Membrane (RC55), 0.45um Pore Size, 47mm Circle (100 pcs) SKU: 10410212

Regenerated Cellulose (RC) Membrane Filters - 10410212

Engineered for high retention efficiency and superior chemical stability, the Whatman 10410212 achieves reliable separation results across a broad range of analytical and preparative applications. Optimized for laboratory use, reproducible separation characteristics define the membrane structure, protecting downstream instruments and preserving sample integrity throughout the filtration process. Accordingly, 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

• Resistant to a wide range of organic solvents including alcohols, ethers, and hydrocarbons that degrade cellulose-based alternatives.
• Regenerated Cellulose offers excellent chemical resistance to both aqueous and organic solvents.
• Symmetric pore geometry provides predictable retention behavior across varying flow rates and pressure conditions.
• Minimal extractable levels make Regenerated Cellulose a reliable choice for analytical applications where background interference must be minimized.
• Mechanically stable and hydrophilic, often used for HPLC mobile phase degassing.

Reproducible particle counting and size distribution analysis start with a membrane surface that captures particles uniformly — the pore consistency documented above ensures your counts reflect the sample, not random variation in the filter. In particular, the hydrophilic nature of RC membranes means you can begin filtering aqueous samples immediately, without the pre-wetting solvent flush that hydrophobic alternatives require — saving time and eliminating a potential source of contamination. Take control of your sample preparation variables and ensure that your data reflects the true nature of your work, rather than the quality of your consumables.

• Organic Solvent Cleaning - Compatible with DMSO and other harsh organics, making it perfect for combinational chemistry sample clarification.
• Tissue Extract Clarification - Handles lipid-rich tissue extracts well, preventing the premature fouling often seen with hydrophobic membrane types.
• Particle Sizing - Used in automated particle counters to provide a clean, non-shedding background for accurate contaminant sizing data.
• Multiplex Bead Assays - Retains microspheres in flow-through assays while allowing the sample matrix to wash away without trapping the beads.
• Microplastic Collection - Filters water samples to capture microplastic fibers, providing a smooth background for microscopic categorization.
• Refractive Index Prep - Ensures absolute optical clarity in filtrates, which is critical for accurate measurements in refractive index detectors.
