MCE Designed for TOC Determinations, .45 um, Prerinsed, 110mm Diameter, 50/Pk SKU: SF181126

Mixed Cellulose Ester (MCE) Membrane Filters - SF181126

Engineered for high retention efficiency and superior chemical stability, the Tisch SF181126 achieves reliable separation results across a broad range of analytical and preparative applications. Moreover, a uniform Mixed Cellulose Ester (MCE) matrix maintains its rated 0.45 cutoff under the pressures and flow conditions encountered during routine laboratory filtration. In sum, from raw polymer through final inspection, the manufacturing process is designed to ensure that every membrane disc meets the performance specifications of its grade designation.

Material Specifications

• Bulk format reduces per-unit packaging waste and cost, appropriate for routine particulate removal and clarification where aseptic handling is not specified.
• 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.
• Rated for continuous operation at temperatures reaching 60°C, enabling filtration of heated solvents and process fluids without material compromise.
• Inherent hydrophilicity enables immediate filtration of water-based samples without alcohol pre-wetting or surfactant conditioning.

Reporting filtration parameters alongside your analytical results demands documented pore size, material chemistry, and lot traceability — the membrane specifications above provide the specificity that reviewers and auditors expect. With this in mind, the high porosity of MCE membranes delivers flow rates that keep your sample throughput practical even at the tighter pore sizes used for bacterial retention and fine particle analysis. Make the decision for consistency and reliability, ensuring that your laboratory maintains its reputation for high-quality, error-free output.
