Mixed Cellulose Ester (MCE) Membrane Filters - 10401606

Precision-manufactured Hydrophilic membrane with a verified 0.45 pore structure delivers consistent retention performance across demanding laboratory filtration workflows. Precision-manufactured Hydrophilic membrane with a verified 0.45 pore structure delivers consistent retention across the full operating range. Precision manufacturing ensures that each membrane disc delivers the rated retention, flow rate, and surface consistency that analytical and microbiological methods require.

Material Specifications

• The biologically inert blend of cellulose acetate and cellulose nitrate provides a membrane surface optimized for organism capture and colony enumeration in microbiological assays.
• Engineered to withstand operating pressures reaching > 10 psi, the construction prevents housing deformation that could compromise membrane retention.
• 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.
• Hydrophilic by nature, the MCE membrane structure supports high non-specific adsorption for effective organism capture.

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. 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. For detailed specification sheets, validation documentation, or technical guidance on membrane selection for your specific application, the Tisch Scientific team is available to support your evaluation.

Hydrophilic

• Vacuum Clarification - Utilized in Buchner funnels to rapidly remove particulates from large-volume batches of non-critical laboratory buffers.
• Sediment Collection - Efficiently harvests precipitates from chemical reactions, allowing for the recovery and drying of the solid synthesis product.
• 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.
• Radiometric Counting - Collects radioactive precipitates for scintillation counting, providing a consistent geometry for accurate data measurement.
• Microscopy mounting - Retains microorganisms on a flat surface, allowing for direct staining and enumeration under a high-power microscope.
