MCE Filter, ME Range (ME 24), Plain, 0.2um Pore Size, 47mm Circle, 100Pk SKU: 10401712

Mixed Cellulose Ester (MCE) Membrane Filters - 10401712

The Whatman 10401712 combines a controlled pore size distribution with low extractable levels, ensuring the data accuracy that sensitive analytical methods require. Underpinning this performance, precision membrane geometry balances retention sharpness with sustainable flow rates, minimizing the pressure buildup that leads to premature filter replacement. In sum, consistent surface properties across the full membrane area support uniform particle capture and reliable results in gravimetric, microscopic, and culture-based analytical workflows.

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.
• 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.
• Non-sterile configuration is suited for analytical sample preparation, mobile phase filtration, and other workflows where pre-sterilization is not required.
• Known for excellent wetting properties and high flow rates in aqueous filtration.
• 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. To address this, 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. Elevate the quality of your analytical data today by standardizing on a filtration product built to meet the exact specifications of your applications.
