ME27 0.8um 50mm 100/Pk SKU: 10400914

Mixed Cellulose Ester (MCE) Membrane Filters - 10400914

The Whatman 10400914 combines a controlled pore size distribution with low extractable levels, ensuring the data accuracy that sensitive analytical methods require. Precision-manufactured Hydrophilic membrane with a verified 0.8 pore structure delivers consistent retention across the full operating range. 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.
• 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.
• Known for excellent wetting properties and high flow rates in aqueous filtration.
• Mixed Cellulose Ester membranes combine cellulose acetate and cellulose nitrate polymers to deliver a smoother, more flexible membrane surface than pure cellulose nitrate.

Environmental monitoring programs where sample-to-sample comparability determines trend validity benefit directly from the lot-level consistency of these membranes, removing the filter as a variable in your long-term data sets. For applications like these, the high porosity of MCE membranes delivers flow rates that keep your sample throughput practical even at the tighter pore sizes used for bacterial retention and fine particle analysis. Make the decision for consistency and reliability, ensuring that your laboratory maintains its reputation for high-quality, error-free output.

Hydrophilic

• Aerosol Analysis - Dissolves completely in acid digestion, allowing for the total chemical analysis of captured airborne metal particulates.
• Chemotaxis Assays - Acts as a barrier in Boyden chambers, allowing cells to migrate through defined pores towards a chemoattractant source.
• Aqueous Filtration - Biologically inert composition provides high flow rates and consistent reliability for routine laboratory fluid processing.
• 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.
• Yeast & Mold Monitoring - Optimized for the recovery of larger fungal organisms in beverage testing, providing a clear background for ID.
