Mixed Cellulose Ester (MCE) Membrane Filters - 10401618

Designed to deliver reproducibility and confidence across critical sample types, the 10401618 provides the filtration consistency that method validation demands. Verified 0.45 pore distribution across the Hydrophilic membrane surface guarantees batch-to-batch consistency in particle capture and analyte passage. Each membrane disc reflects a manufacturing standard where retention characteristics, physical integrity, and dimensional accuracy are verified before release.

Material Specifications

• 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.
• Materials of construction maintain their mechanical and chemical properties at temperatures up to 130°C, supporting heated filtration protocols.
• Hydrophilic by nature, the MCE membrane structure supports high non-specific adsorption for effective organism capture.
• Mixed Cellulose Ester membranes combine cellulose acetate and cellulose nitrate polymers to deliver a smoother, more flexible membrane surface than pure cellulose nitrate.
• Known for excellent wetting properties and high flow rates in aqueous filtration.

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. 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 questions about chemical compatibility, operating limits, or equivalent product cross-references, Tisch Scientific's filtration specialists can provide the technical detail your method documentation requires.

Hydrophilic

• Gravimetric Analysis - Captures total suspended solids from liquid samples on a weighed disc, ensuring accurate mass measurements for reporting.
• Radiometric Counting - Collects radioactive precipitates for scintillation counting, providing a consistent geometry for accurate data measurement.
• Stack Pre-filtration - Acts as a spacer or depth layer in multi-tier filtration stacks to extend the life of the final downstream membrane.
• Sediment Collection - Efficiently harvests precipitates from chemical reactions, allowing for the recovery and drying of the solid synthesis product.
• 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.
