MCE Membrane Filter, Hydrophilic, 0.45µm, 47mm, Nonsterile, Biological Inert, 100/Pk SKU: LE-IWT-MCE045047

Featuring biologically inert mixed cellulose ester membrane technology delivering superior surface uniformity and enhanced handling characteristics for precision microfiltration applications. A balanced blend of cellulose acetate and cellulose nitrate creates smoother, more uniform surfaces compared to pure nitrocellulose filters, while providing exceptional flow rates and reduced cracking during filtration procedures. Naturally low metal background construction ensures compatibility with dilute acids, bases, and aromatic and aliphatic hydrocarbons for versatile laboratory applications.

Key MCE Membrane Characteristics

Hydrophilic surface chemistry allows immediate wetting without pre-treatment, accelerating aqueous solution processing
0.45 µm pore size provides precise particle retention with optimized flow characteristics for medium-fast filtration
Biologically inert composition eliminates organic contamination while maintaining chemical stability across pH ranges
Ultra-low metal content delivers contamination-free results for atomic absorption spectroscopy and trace analysis
Readily digested by dilute nitric acid making it ideal for atomic absorption spectroscopic analysis

Key Construction Characteristics

47mm diameter accommodates standard filter holders and manifold systems for high-throughput processing
Pure surface construction without additional smoothing treatments or surfactants maintains sample integrity
Clean-edge processing ensures easy separation from filter stacks and minimizes curling during handling
Autoclavable design withstands sterilization protocols for sterile filtration requirements
Bright white appearance provides excellent visual contrast for particle detection and colony counting applications

LE-IWT-MCE045047 filters achieve exceptional medium-fast flow rates with reproducible loading capacity, maximizing your analytical throughput for aqueous sample preparation and biological specimen processing. Meeting NIOSH and OSHA method specifications for monitoring airborne metals and fibers, these filters transform routine laboratory procedures into validated analytical protocols. Versatile compatibility with HPLC sample preparation, cytology, yeast and mold concentration, and microbiological QA/QC applications delivers comprehensive filtration solutions for food and beverage testing, pharmaceutical analysis, and environmental water sample clarification requiring both precision particle retention and superior chemical compatibility.
