ME25/41 ST 0.45um 47mm 100/Pk SKU: 10409470

Mixed Cellulose Ester (MCE) Membrane Filters - 10409470

Precision-manufactured Hydrophilic membrane with a verified 0.45 pore structure delivers consistent retention performance across demanding laboratory filtration workflows. Precision-manufactured Hydrophilic membrane with a verified 0.45 pore structure delivers consistent retention across the full operating range. Working in concert, controlled production conditions produce membranes with documented pore size distribution and thickness tolerances, supporting method reproducibility across multiple filter lots.

Material Specifications

• 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.
• Mixed Cellulose Ester membranes combine cellulose acetate and cellulose nitrate polymers to deliver a smoother, more flexible membrane surface than pure cellulose nitrate.
• 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.
• Hydrophilic by nature, the MCE membrane structure supports high non-specific adsorption for effective organism capture.

When your analytical method specifies membrane filtration as a sample preparation step, the retention characteristics and extractable profiles documented above allow you to meet method requirements without additional qualification work. Low background interference from mixed cellulose ester membranes means your gravimetric measurements reflect the mass of captured particles, not membrane extractables — reducing the blank corrections that add uncertainty to your weight-based analyses. 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.

• Black Grid Analysis - Black membrane variants enhance contrast for light-colored colonies, reducing eye strain during manual plate counting.
• Yeast & Mold Monitoring - Optimized for the recovery of larger fungal organisms in beverage testing, providing a clear background for ID.
• Biochemical Assays - High electrostatic properties effectively bind proteins and macromolecules, supporting various diagnostic and research assays.
• Microscopy mounting - Can be made transparent with immersion oil, allowing for direct light microscopy of retained particles on the surface.
• Gravimetric Analysis - Maintains structural integrity during filtration and drying, providing precise weight measurements of retained particulates.
• Aqueous Filtration - Biologically inert composition provides high flow rates and consistent reliability for routine laboratory fluid processing.
