ME27/61 ST 0.8um 47mm 100/Pk SKU: 10409970

Mixed Cellulose Ester (MCE) Membrane Filters - 10409970

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. 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

• The biologically inert blend of cellulose acetate and cellulose nitrate provides a membrane surface optimized for organism capture and colony enumeration in microbiological assays.
• Feature a uniform pore structure that provides consistent flow rates and high throughputs across the full range of standard pore size ratings.
• 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.
• Mixed Cellulose Ester membranes combine cellulose acetate and cellulose nitrate polymers to deliver a smoother, more flexible membrane surface than pure cellulose nitrate.
• Known for excellent wetting properties and high flow rates in aqueous filtration.

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. The uniform surface structure of mixed cellulose ester membranes provides the optically flat background that your microscopy and particulate analysis methods require for accurate visualization and particle counting. Elevate the quality of your analytical data today by standardizing on a filtration product built to meet the exact specifications of your applications.

Hydrophilic

• Aqueous Filtration - Biologically inert composition provides high flow rates and consistent reliability for routine laboratory fluid processing.
• Black Grid Analysis - Black membrane variants enhance contrast for light-colored colonies, reducing eye strain during manual plate counting.
• Yeast & Mold Monitoring - Optimized for the recovery of larger fungal organisms in beverage testing, providing a clear background for ID.
• Chemotaxis Assays - Acts as a barrier in Boyden chambers, allowing cells to migrate through defined pores towards a chemoattractant source.
• Gravimetric Analysis - Maintains structural integrity during filtration and drying, providing precise weight measurements of retained particulates.
• Bioburden Monitoring - Routine testing of pharmaceutical water loops to ensure bioburden levels remain within safe production specifications.
