ME26 0.6um 25mm 100/Pk SKU: 10401506

Mixed Cellulose Ester (MCE) Membrane Filters - 10401506

The Whatman 10401506 combines a controlled pore size distribution with low extractable levels, ensuring the data accuracy that sensitive analytical methods require. A uniform Mixed Cellulose Ester (MCE) matrix maintains its rated 0.6 cutoff under the pressures and flow conditions encountered during routine laboratory filtration. Precision manufacturing ensures that each membrane disc delivers the rated retention, flow rate, and surface consistency that analytical and microbiological methods require.

Material Specifications

• Bulk format reduces per-unit packaging waste and cost, appropriate for routine particulate removal and clarification where aseptic handling is not specified.
• Feature a uniform pore structure that provides consistent flow rates and high throughputs across the full range of standard pore size ratings.
• 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.
• 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. Specifically, low background interference from mixed cellulose ester membranes means your gravimetric measurements reflect the mass of captured particles, not membrane extractables — reducing the blank corrections that add uncertainty to your weight-based analyses. Secure your research outcomes by partnering with a filtration solution that understands your need for speed, accuracy, and reproducibility.
