ME27 0.8um 25mm 100/Pk SKU: 10400906

Mixed Cellulose Ester (MCE) Membrane Filters - 10400906

Precision-manufactured Hydrophilic membrane with a verified 0.8 pore structure delivers consistent retention performance across demanding laboratory filtration workflows. Reproducible separation characteristics define the membrane structure, protecting downstream instruments and preserving sample integrity throughout the filtration process. Accordingly, 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

• Mixed Cellulose Ester membranes combine cellulose acetate and cellulose nitrate polymers to deliver a smoother, more flexible membrane surface than pure cellulose nitrate.
• Non-sterile configuration is suited for analytical sample preparation, mobile phase filtration, and other workflows where pre-sterilization is not required.
• 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.
• 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.

When your analytical method specifies membrane filtration as a sample preparation step, the retention characteristics and extractable profiles documented above allow you to meet method requirements without additional qualification work. For this application, MCE's naturally hydrophilic surface allows immediate wetting upon contact with aqueous samples, eliminating the pre-conditioning step and letting you begin filtration as soon as the membrane is seated in your holder. Secure your research outcomes by partnering with a filtration solution that understands your need for speed, accuracy, and reproducibility.
