Mixed Cellulose Ester (MCE) Membrane Filters - 10406970
The Whatman 10406970 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 0.2 pore structure delivers consistent retention across the full operating range. Working in concert, controlled production conditions produce membranes with documented pore size distribution and thickness tolerances, supporting method reproducibility across multiple filter lots.
Material Specifications
- The biologically inert blend of cellulose acetate and cellulose nitrate provides a membrane surface optimized for organism capture and colony enumeration in microbiological assays.
- 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.
- 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.
- Pre-sterilized packaging eliminates the need for in-house autoclaving, reducing preparation time and ensuring consistent sterility from lot to lot.
Whether your method calls for gravimetric analysis, particle visualization, or microbial enumeration, the pore consistency and surface uniformity documented above ensure that your results reflect the sample — not the filter. For exactly this reason, 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. Take control of your sample preparation variables and ensure that your data reflects the true nature of your work, rather than the quality of your consumables.
