Mixed Cellulose Ester (MCE) Membrane Filters - 10400714

Engineered for high retention efficiency and superior chemical stability, the 10400714 achieves reliable separation results across a broad range of analytical and preparative applications. Precision-manufactured Hydrophilic membrane with a verified 3.0 pore structure delivers consistent retention across the full operating range. Each membrane disc reflects a manufacturing standard where retention characteristics, physical integrity, and dimensional accuracy are verified before release.

Material Specifications

• Hydrophilic by nature, the MCE membrane structure supports high non-specific adsorption for effective organism capture.
• Rated for continuous operation at temperatures reaching 130°C, enabling filtration of heated solvents and process fluids without material compromise.
• The biologically inert blend of cellulose acetate and cellulose nitrate provides a membrane surface optimized for organism capture and colony enumeration in microbiological assays.
• Known for excellent wetting properties and high flow rates in aqueous filtration.
• Supplied in bulk non-sterile packaging, offering an economical option for routine clarification and general laboratory filtration tasks.

Reproducible particle counting and size distribution analysis start with a membrane surface that captures particles uniformly — the pore consistency documented above ensures your counts reflect the sample, not random variation in the filter. MCE's naturally hydrophilic surface allows immediate wetting upon contact with aqueous samples, eliminating the pre-conditioning step and letting you begin filtration as soon as the membrane is seated in your holder. 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.

Hydrophilic

• Quality Control Testing - Serves as a standard check filter for routine batch purity tests, verifying the absence of visible physical contaminants.
• 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.
• Sediment Collection - Efficiently harvests precipitates from chemical reactions, allowing for the recovery and drying of the solid synthesis product.
• Vacuum Clarification - Utilized in Buchner funnels to rapidly remove particulates from large-volume batches of non-critical laboratory buffers.
• Microscopy mounting - Retains microorganisms on a flat surface, allowing for direct staining and enumeration under a high-power microscope.
