WME WHGRSTNPD 47mm 0.45 100/Pk SKU: 7141-114

Mixed Cellulose Ester (MCE) Membrane Filters - 7141-114

Precision-manufactured Hydrophilic membrane with a verified 0.45 pore structure delivers consistent retention performance across demanding laboratory filtration workflows. At its core, verified 0.45 pore distribution across the Hydrophilic membrane surface guarantees batch-to-batch consistency in particle capture and analyte passage. Lot-level verification of pore size, flow rate, and physical dimensions ensures that membrane performance remains predictable when scaling from method development to routine analysis.

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.
• Hydrophilic by nature, the MCE membrane structure supports high non-specific adsorption for effective organism capture.
• Supplied in bulk non-sterile packaging, offering an economical option for routine clarification and general laboratory filtration tasks.
• 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.
• Known for excellent wetting properties and high flow rates in aqueous filtration.

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. For applications like these, 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.
