Mixed Cellulose Ester (MCE) Membrane Filters - 10408712

Precision-manufactured Hydrophilic membrane with a verified 0.2 pore structure delivers consistent retention performance across demanding laboratory filtration workflows. Precision-manufactured Hydrophilic membrane with a verified 0.2 pore structure delivers consistent retention across the full operating range. In combination, 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

• 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.
• Bulk packaging format provides cost-effective access for high-volume laboratories performing non-critical filtration and sample preparation.
• The biologically inert blend of cellulose acetate and cellulose nitrate provides a membrane surface optimized for organism capture and colony enumeration in microbiological assays.
• Hydrophilic by nature, the MCE membrane structure supports high non-specific adsorption for effective organism capture.
• Feature a uniform pore structure that provides consistent flow rates and high throughputs across the full range of standard pore size ratings.

Transitioning from qualitative screening to quantitative gravimetric analysis requires a membrane with documented tare weight consistency, and the manufacturing tolerances above ensure that your blank values remain within acceptable limits. 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. Make the decision for consistency and reliability, ensuring that your laboratory maintains its reputation for high-quality, error-free output.

Wettability

Hydrophilic

• 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.
• Water Quality Testing - Features a gridded surface for easy colony counting, essential for regulatory compliance in municipal water quality labs.
• Black Grid Analysis - Black membrane variants enhance contrast for light-colored colonies, reducing eye strain during manual plate counting.
• Aqueous Filtration - Biologically inert composition provides high flow rates and consistent reliability for routine laboratory fluid processing.
