Mixed Cellulose Ester (MCE) Membrane Filters - 10401514

The 10401514 protects sensitive instrumentation and sample integrity by providing reliable particulate removal with minimal analyte adsorption or background interference. A uniform Mixed Cellulose Ester (MCE) matrix maintains its rated 0.6 cutoff under the pressures and flow conditions encountered during routine laboratory filtration. Precision manufacturing ensures that each membrane disc delivers the rated retention, flow rate, and surface consistency that analytical and microbiological methods require.

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.
• A > 10 psi pressure rating provides confidence that the device will maintain seal integrity and membrane performance under demanding filtration conditions.
• 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.

Transitioning from qualitative screening to quantitative gravimetric analysis requires a membrane with documented tare weight consistency, and the manufacturing tolerances above ensure that your blank values remain within acceptable limits. 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. If your laboratory requires volume pricing, custom packaging configurations, or scheduled delivery programs, the Tisch Scientific sales team can structure a supply arrangement matched to your consumption rate.

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