MCE Filter, ME Range (ME 24), Plain, 0.2um Pore Size, 110mm, 50pk SKU: 10401726

Mixed Cellulose Ester (MCE) Membrane Filters - 10401726

The Whatman 10401726 combines a controlled pore size distribution with low extractable levels, ensuring the data accuracy that sensitive analytical methods require. In addition, quality-controlled manufacturing ensures the filtration medium delivers the retention efficiency and throughput that demanding laboratory protocols require. Accordingly, precision manufacturing ensures that each membrane disc delivers the rated retention, flow rate, and surface consistency that analytical and microbiological methods require.

Material Specifications

• Known for excellent wetting properties and high flow rates in aqueous filtration.
• 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.
• Bulk format reduces per-unit packaging waste and cost, appropriate for routine particulate removal and clarification where aseptic handling is not specified.
• The biologically inert blend of cellulose acetate and cellulose nitrate provides a membrane surface optimized for organism capture and colony enumeration in microbiological assays.

Air monitoring and stack emissions sampling demand a filter medium that withstands the thermal and chemical conditions at your collection point — the material properties described above define the operating envelope for your application. 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

• Aqueous Filtration - Biologically inert composition provides high flow rates and consistent reliability for routine laboratory fluid processing.
• Gravimetric Analysis - Maintains structural integrity during filtration and drying, providing precise weight measurements of retained particulates.
• Bioburden Monitoring - Routine testing of pharmaceutical water loops to ensure bioburden levels remain within safe production specifications.
• Yeast & Mold Monitoring - Optimized for the recovery of larger fungal organisms in beverage testing, providing a clear background for ID.
• 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.
