Mixed Cellulose Ester (MCE) Membrane Filters - 10401731

Engineered for high retention efficiency and superior chemical stability, the Whatman 10401731 achieves reliable separation results across a broad range of analytical and preparative applications. Engineered for demanding applications, a uniform Mixed Cellulose Ester (MCE) matrix maintains its rated 0.2 cutoff under the pressures and flow conditions encountered during routine laboratory filtration. Accordingly, 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.
• 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.
• Supplied in bulk non-sterile packaging, offering an economical option for routine clarification and general laboratory filtration tasks.
• Mixed Cellulose Ester membranes combine cellulose acetate and cellulose nitrate polymers to deliver a smoother, more flexible membrane surface than pure cellulose nitrate.

If your protocol requires direct on-membrane analysis by microscopy or culture, the surface characteristics and dimensional tolerances described above give you a substrate that performs consistently from disc to disc. With these demands in mind, MCE's well-documented retention characteristics at standard pore ratings make it straightforward to specify in your method documentation, supporting the reproducibility and traceability that regulated workflows demand. 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.

Wettability

Hydrophilic

• Aqueous Filtration - Biologically inert composition provides high flow rates and consistent reliability for routine laboratory fluid processing.
• Chemotaxis Assays - Acts as a barrier in Boyden chambers, allowing cells to migrate through defined pores towards a chemoattractant source.
• Microscopy mounting - Can be made transparent with immersion oil, allowing for direct light microscopy of retained particles on the surface.
• Water Quality Testing - Features a gridded surface for easy colony counting, essential for regulatory compliance in municipal water quality labs.
• 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.
