ME26/31 0.6um 50mm 100/Pk SKU: 10409814

Mixed Cellulose Ester (MCE) Membrane Filters - 10409814

The Whatman 10409814 protects sensitive instrumentation and sample integrity by providing reliable particulate removal with minimal analyte adsorption or background interference. Additionally, precision-manufactured Hydrophilic membrane with a verified 0.6 pore structure delivers consistent retention across the full operating range. 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

• Economical bulk packaging supports laboratories with high consumable throughput where individual sterile wrapping is unnecessary.
• Known for excellent wetting properties and high flow rates in aqueous filtration.
• Feature a uniform pore structure that provides consistent flow rates and high throughputs across the full range of standard pore size ratings.
• 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.
• Hydrophilic by nature, the MCE membrane structure supports high non-specific adsorption for effective organism capture.

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. For this purpose, the uniform surface structure of mixed cellulose ester membranes provides the optically flat background that your microscopy and particulate analysis methods require for accurate visualization and particle counting. 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.

• Water Quality Testing - Features a gridded surface for easy colony counting, essential for regulatory compliance in municipal water quality labs.
• Microscopy mounting - Can be made transparent with immersion oil, allowing for direct light microscopy of retained particles on the surface.
• Aqueous Filtration - Biologically inert composition provides high flow rates and consistent reliability for routine laboratory fluid processing.
• Gravimetric Analysis - Maintains structural integrity during filtration and drying, providing precise weight measurements of retained particulates.
• Aerosol Analysis - Dissolves completely in acid digestion, allowing for the total chemical analysis of captured airborne metal particulates.
• Black Grid Analysis - Black membrane variants enhance contrast for light-colored colonies, reducing eye strain during manual plate counting.
