MCE Filter, ME Range (ME 24), Plain, 0.2um Pore Size, 100mm, 50Pk SKU: 10401721

Mixed Cellulose Ester (MCE) Membrane Filters - 10401721

The Whatman 10401721 combines a controlled pore size distribution with low extractable levels, ensuring the data accuracy that sensitive analytical methods require. Built for consistent results, precision membrane geometry balances retention sharpness with sustainable flow rates, minimizing the pressure buildup that leads to premature filter replacement. 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

• Bulk format reduces per-unit packaging waste and cost, appropriate for routine particulate removal and clarification where aseptic handling is not specified.
• Mixed Cellulose Ester membranes combine cellulose acetate and cellulose nitrate polymers to deliver a smoother, more flexible membrane surface than pure cellulose nitrate.
• Hydrophilic by nature, the MCE membrane structure supports high non-specific adsorption for effective organism capture.
• Low tare weight and complete solubility in organic solvents make MCE the standard membrane for gravimetric particulate analysis where method specifications demand minimal blank correction.
• The biologically inert blend of cellulose acetate and cellulose nitrate provides a membrane surface optimized for organism capture and colony enumeration in microbiological assays.

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, because mixed cellulose ester membranes dissolve completely in specific organic solvents, you can recover captured particles from the membrane surface for further analysis — a capability that no other common membrane type provides. Make the decision for consistency and reliability, ensuring that your laboratory maintains its reputation for high-quality, error-free output.
