Mixed Cellulose Ester (MCE) Membrane Filters - 10400912

Precision-manufactured Hydrophilic membrane with a verified 0.8 pore structure delivers consistent retention performance across demanding laboratory filtration workflows. Precision membrane geometry balances retention sharpness with sustainable flow rates, minimizing the pressure buildup that leads to premature filter replacement. Each membrane disc reflects a manufacturing standard where retention characteristics, physical integrity, and dimensional accuracy are verified before release.

Material Specifications

• Packaged without sterilization for applications where downstream sterility is achieved by other means or is not a process requirement.
• Hydrophilic by nature, the MCE membrane structure supports high non-specific adsorption for effective organism capture.
• Maximum operating temperature of 130°C accommodates warm sample filtration and elevated-temperature processes that exceed the limits of standard devices.
• 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.

Whether your method calls for gravimetric analysis, particle visualization, or microbial enumeration, the pore consistency and surface uniformity documented above ensure that your results reflect the sample — not the filter. Low background interference from mixed cellulose ester membranes means your gravimetric measurements reflect the mass of captured particles, not membrane extractables — reducing the blank corrections that add uncertainty to your weight-based analyses. Sample quantities for method validation and compatibility testing are available through Tisch Scientific — request a sample to verify performance in your specific workflow before committing to a production volume.

• Microscopy mounting - Retains microorganisms on a flat surface, allowing for direct staining and enumeration under a high-power microscope.
• Quality Control Testing - Serves as a standard check filter for routine batch purity tests, verifying the absence of visible physical contaminants.
• Air Particulate Sampling - Traps airborne dust and pollen on a positioned open-face filter disc for subsequent microscopic or chemical analysis.
• Radiometric Counting - Collects radioactive precipitates for scintillation counting, providing a consistent geometry for accurate data measurement.
• Sediment Collection - Efficiently harvests precipitates from chemical reactions, allowing for the recovery and drying of the solid synthesis product.
• Gravimetric Analysis - Captures total suspended solids from liquid samples on a weighed disc, ensuring accurate mass measurements for reporting.
