Mixed Cellulose Ester (MCE) Membrane Filters - 10401614

Precision-manufactured Hydrophilic membrane with a verified 0.45 pore structure delivers consistent retention performance across demanding laboratory filtration workflows. Quality-controlled manufacturing ensures the filtration medium delivers the retention efficiency and throughput that demanding laboratory protocols require. 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

• Rated for a maximum operating pressure of > 10 psi, providing the structural margin required for high-viscosity and high-volume filtration runs.
• The biologically inert blend of cellulose acetate and cellulose nitrate provides a membrane surface optimized for organism capture and colony enumeration in microbiological assays.
• Mixed Cellulose Ester membranes combine cellulose acetate and cellulose nitrate polymers to deliver a smoother, more flexible membrane surface than pure cellulose nitrate.
• Thermal stability of the construction materials allows safe operation at temperatures up to 130°C without degradation of membrane or housing performance.
• Hydrophilic by nature, the MCE membrane structure supports high non-specific adsorption for effective organism capture.

Environmental monitoring programs where sample-to-sample comparability determines trend validity benefit directly from the lot-level consistency of these membranes, removing the filter as a variable in your long-term data sets. 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. Complete product specifications, certificates of analysis, and lot-specific documentation to support your quality system requirements are available through Tisch Scientific upon request.

Hydrophilic

• Air Particulate Sampling - Traps airborne dust and pollen on a positioned open-face filter disc for subsequent microscopic or chemical analysis.
• Stack Pre-filtration - Acts as a spacer or depth layer in multi-tier filtration stacks to extend the life of the final downstream membrane.
• Vacuum Clarification - Utilized in Buchner funnels to rapidly remove particulates from large-volume batches of non-critical laboratory buffers.
• Quality Control Testing - Serves as a standard check filter for routine batch purity tests, verifying the absence of visible physical contaminants.
• Microscopy mounting - Retains microorganisms on a flat surface, allowing for direct staining and enumeration under a high-power microscope.
• Gravimetric Analysis - Captures total suspended solids from liquid samples on a weighed disc, ensuring accurate mass measurements for reporting.
