ME25/21 ST 0.45um 47mm 1000/Pk SKU: 10406871

Mixed Cellulose Ester (MCE) Membrane Filters - 10406871

Precision-manufactured Hydrophilic membrane with a verified 0.45 pore structure delivers consistent retention performance across demanding laboratory filtration workflows. Built for consistent results, precision membrane geometry balances retention sharpness with sustainable flow rates, minimizing the pressure buildup that leads to premature filter replacement. Consistent surface properties across the full membrane area support uniform particle capture and reliable results in gravimetric, microscopic, and culture-based analytical workflows.

Material Specifications

• Hydrophilic by nature, the MCE membrane structure supports high non-specific adsorption for effective organism capture.
• Pre-sterilized packaging eliminates the need for in-house autoclaving, reducing preparation time and ensuring consistent sterility from lot to lot.
• Known for excellent wetting properties and high flow rates in aqueous filtration.
• 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.

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. Here, 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. Elevate the quality of your analytical data today by standardizing on a filtration product built to meet the exact specifications of your applications.
