MCE Circle ME Range (ME 25), Plain, 0.45um Pore Size, 110mm, 50pk SKU: 10401626

Mixed Cellulose Ester (MCE) Membrane Filters - 10401626

Designed to deliver reproducibility and confidence across critical sample types, the Whatman 10401626 provides the filtration consistency that method validation demands. Reproducible separation characteristics define the membrane structure, protecting downstream instruments and preserving sample integrity throughout the filtration process. Each membrane disc reflects a manufacturing standard where retention characteristics, physical integrity, and dimensional accuracy are verified before release.

Material Specifications

• 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.
• 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.

Transitioning from qualitative screening to quantitative gravimetric analysis requires a membrane with documented tare weight consistency, and the manufacturing tolerances above ensure that your blank values remain within acceptable limits. 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. Secure your research outcomes by partnering with a filtration solution that understands your need for speed, accuracy, and reproducibility.

Wettability

Hydrophilic

• Microscopy mounting - Can be made transparent with immersion oil, allowing for direct light microscopy of retained particles on the surface.
• Aerosol Analysis - Dissolves completely in acid digestion, allowing for the total chemical analysis of captured airborne metal particulates.
• Bioburden Monitoring - Routine testing of pharmaceutical water loops to ensure bioburden levels remain within safe production specifications.
• Aqueous Filtration - Biologically inert composition provides high flow rates and consistent reliability for routine laboratory fluid processing.
• Biochemical Assays - High electrostatic properties effectively bind proteins and macromolecules, supporting various diagnostic and research assays.
• Chemotaxis Assays - Acts as a barrier in Boyden chambers, allowing cells to migrate through defined pores towards a chemoattractant source.
