MCE Circle ME Range (ME 25), Green/Black Grid 3.1mm, 0.45um, 47mm, 1000 /Pk SKU: 10409414

Mixed Cellulose Ester (MCE) Membrane Filters - 10409414

The Whatman 10409414 protects sensitive instrumentation and sample integrity by providing reliable particulate removal with minimal analyte adsorption or background interference. Precision-manufactured Hydrophilic membrane with a verified 0.45 pore structure delivers consistent retention across the full operating range. As a result, 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

• Feature a uniform pore structure that provides consistent flow rates and high throughputs across the full range of standard pore size ratings.
• 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.
• Packaged without sterilization for applications where downstream sterility is achieved by other means or is not a process requirement.
• Hydrophilic by nature, the MCE membrane structure supports high non-specific adsorption for effective organism capture.
• Known for excellent wetting properties and high flow rates in aqueous filtration.

If your protocol requires direct on-membrane analysis by microscopy or culture, the surface characteristics and dimensional tolerances described above give you a substrate that performs consistently from disc to disc. In these cases, MCE's well-documented retention characteristics at standard pore ratings make it straightforward to specify in your method documentation, supporting the reproducibility and traceability that regulated workflows demand. Make the decision for consistency and reliability, ensuring that your laboratory maintains its reputation for high-quality, error-free output.
