Mixed Cellulose Ester (MCE) Membrane Filters - 10401770
Precision-manufactured Hydrophilic membrane with a verified 0.2 pore structure delivers consistent retention performance across demanding laboratory filtration workflows. Optimized for laboratory use, precision membrane geometry balances retention sharpness with sustainable flow rates, minimizing the pressure buildup that leads to premature filter replacement. To this end, 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
- Mixed Cellulose Ester membranes combine cellulose acetate and cellulose nitrate polymers to deliver a smoother, more flexible membrane surface than pure cellulose nitrate.
- The biologically inert blend of cellulose acetate and cellulose nitrate provides a membrane surface optimized for organism capture and colony enumeration in microbiological assays.
- Packaged without sterilization for applications where downstream sterility is achieved by other means or is not a process requirement.
- 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.
- Feature a uniform pore structure that provides consistent flow rates and high throughputs across the full range of standard pore size ratings.
Reproducible particle counting and size distribution analysis start with a membrane surface that captures particles uniformly — the pore consistency documented above ensures your counts reflect the sample, not random variation in the filter. Because mixed cellulose ester membranes dissolve completely in specific organic solvents, you can recover captured particles from the membrane surface for further analysis — a capability that no other common membrane type provides. 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.
