Mixed Cellulose Ester (MCE) Membrane Filters - 10401512

Engineered for high retention efficiency and superior chemical stability, the 10401512 achieves reliable separation results across a broad range of analytical and preparative applications. A uniform Mixed Cellulose Ester (MCE) matrix maintains its rated 0.6 cutoff under the pressures and flow conditions encountered during routine laboratory filtration. Controlled production conditions produce membranes with documented pore size distribution and thickness tolerances, supporting method reproducibility across multiple filter lots.

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.
• Bulk format reduces per-unit packaging waste and cost, appropriate for routine particulate removal and clarification where aseptic handling is not specified.
• Materials of construction maintain their mechanical and chemical properties at temperatures up to 130°C, supporting heated filtration protocols.
• The biologically inert blend of cellulose acetate and cellulose nitrate provides a membrane surface optimized for organism capture and colony enumeration in microbiological assays.

Maintaining accreditation under ISO 17025 or similar quality frameworks requires documented traceability at every step — the specification compliance of each membrane lot supports your ongoing audit readiness. Because mixed cellulose ester membranes dissolve completely in specific organic solvents, you can recover captured particles from the membrane surface for further analysis — a capability that no other common membrane type provides. 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.

• 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.
• Vacuum Clarification - Utilized in Buchner funnels to rapidly remove particulates from large-volume batches of non-critical laboratory buffers.
• 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.
