ME28 1.2um 47mm 100/Pk SKU: 10400812

Mixed Cellulose Ester (MCE) Membrane Filters - 10400812

Precision-manufactured Hydrophilic membrane with a verified 1.2 pore structure delivers consistent retention performance across demanding laboratory filtration workflows. Designed for laboratory performance, verified 1.2 pore distribution across the Hydrophilic membrane surface guarantees batch-to-batch consistency in particle capture and analyte passage. Together, precision manufacturing ensures that each membrane disc delivers the rated retention, flow rate, and surface consistency that analytical and microbiological methods require.

Material Specifications

• Bulk packaging format provides cost-effective access for high-volume laboratories performing non-critical filtration and sample preparation.
• Mixed Cellulose Ester membranes combine cellulose acetate and cellulose nitrate polymers to deliver a smoother, more flexible membrane surface than pure cellulose nitrate.
• Hydrophilic by nature, the MCE membrane structure supports high non-specific adsorption for effective organism capture.
• The biologically inert blend of cellulose acetate and cellulose nitrate provides a membrane surface optimized for organism capture and colony enumeration in microbiological assays.
• Known for excellent wetting properties and high flow rates in aqueous filtration.

Reporting filtration parameters alongside your analytical results demands documented pore size, material chemistry, and lot traceability — the membrane specifications above provide the specificity that reviewers and auditors expect. In particular, MCE's naturally hydrophilic surface allows immediate wetting upon contact with aqueous samples, eliminating the pre-conditioning step and letting you begin filtration as soon as the membrane is seated in your holder. Elevate the quality of your analytical data today by standardizing on a filtration product built to meet the exact specifications of your applications.

Wettability

Hydrophilic

• Microscopy mounting - Can be made transparent with immersion oil, allowing for direct light microscopy of retained particles on the surface.
• Chemotaxis Assays - Acts as a barrier in Boyden chambers, allowing cells to migrate through defined pores towards a chemoattractant source.
• 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.
• Biochemical Assays - High electrostatic properties effectively bind proteins and macromolecules, supporting various diagnostic and research assays.
• Black Grid Analysis - Black membrane variants enhance contrast for light-colored colonies, reducing eye strain during manual plate counting.
