MCE Membrane Filter, Hydrophilic, 0.45 µm, 25mm, Nonsterile - Mixed Cellulose Ester, 100/Pk SKU: LE-IWT-MCE045025

Featuring hydrophilic mixed cellulose ester membrane technology delivering superior flow rates and exceptional particle retention for demanding analytical and microbiological applications. Comprised of pure, biologically inert mixtures of cellulose acetate and cellulose nitrate, these 0.45 µm pore size membranes provide smoother and more uniform surface than pure nitrocellulose filter while maintaining precise filtration characteristics essential for laboratory protocols and quality control procedures.

Key MCE Membrane Characteristics

• Hydrophilic surface chemistry ensures rapid wetting and consistent flow rates with aqueous solutions and biological samples
• 0.45 µm nominal pore size delivers reliable particle retention and bacterial filtration for sterile sample preparation
• Naturally low in metal background and exhibits low protein-binding properties for trace analysis and life science applications
• Biologically inert construction eliminates interference in microbiological assays and analytical determinations
• Fast flow rates and high protein binding capacity with great thermal stability maximize throughput in diagnostic applications

Key Construction Characteristics

• 25mm diameter format provides optimal surface area for syringe filtration and small-volume sample processing
• Sterilization compatibility through autoclaving, gamma irradiation, or ethylene oxide gas sterilization enables sterile application protocols
• Improved flatness and uniformity with high pore diameter accuracy, strength and toughness prevents tearing during handling
• Residue of less than 0.045% of initial weight in gravimetric analysis using ashing techniques ensures analytical accuracy
• Compatible with dilute bases and acids and aromatic and aliphatic hydrocarbons providing chemical versatility

These nonsterile MCE membrane filters achieve exceptional performance in air monitoring, AAS (Atomic Absorption Spectroscopy analysis), ICP (Inductively Coupled Plasma analysis) and transmitted light microscopy applications. Meeting NIOSH and OSHA method specifications for monitoring airborne metals¹, these filters deliver validated results for environmental compliance and industrial hygiene protocols. Outstanding versatility accommodates HPLC sample preparation, cytology applications, microbiological QA/QC procedures, and food and beverage analysis while providing the analytical reliability demanded by regulatory testing environments.
