MCE Circle ME Range (ME 25), Plain, 0.45um Pore Size, 47mm, 100pk SKU: 10401612

Mixed Cellulose Ester (MCE) Membrane Filters - 10401612

Designed to deliver reproducibility and confidence across critical sample types, the Whatman 10401612 provides the filtration consistency that method validation demands. Built for consistent results, verified 0.45 pore distribution across the Hydrophilic membrane surface guarantees batch-to-batch consistency in particle capture and analyte passage. By design, controlled production conditions produce membranes with documented pore size distribution and thickness tolerances, supporting method reproducibility across multiple filter lots.

Material Specifications

• Mixed Cellulose Ester membranes combine cellulose acetate and cellulose nitrate polymers to deliver a smoother, more flexible membrane surface than pure cellulose nitrate.
• Feature a uniform pore structure that provides consistent flow rates and high throughputs across the full range of standard pore size ratings.
• Known for excellent wetting properties and high flow rates in aqueous filtration.
• The biologically inert blend of cellulose acetate and cellulose nitrate provides a membrane surface optimized for organism capture and colony enumeration in microbiological assays.
• Hydrophilic by nature, the MCE membrane structure supports high non-specific adsorption for effective organism capture.

Maintaining accreditation under ISO 17025 or similar quality frameworks requires documented traceability at every step — the specification compliance of each membrane lot supports your ongoing audit readiness. Meeting this challenge, 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. Elevate the quality of your analytical data today by standardizing on a filtration product built to meet the exact specifications of your applications.

Hydrophilic

• Aerosol Analysis - Dissolves completely in acid digestion, allowing for the total chemical analysis of captured airborne metal particulates.
• Biochemical Assays - High electrostatic properties effectively bind proteins and macromolecules, supporting various diagnostic and research assays.
• Gravimetric Analysis - Maintains structural integrity during filtration and drying, providing precise weight measurements of retained particulates.
• Yeast & Mold Monitoring - Optimized for the recovery of larger fungal organisms in beverage testing, providing a clear background for ID.
• 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.
