Cellulose Acetate Syringe Filter, 0.22µm, 25mm, Luer-Lok, Nonsterile, 100/Pk SKU: LE-IWT-ES10083

Featuring hydrophilic cellulose acetate membrane technology delivering exceptional protein recovery and sample integrity for demanding analytical workflows. Low inherent protein binding characteristics ensure maximum recovery while 0.22µm pore size provides reliable bacterial retention and particulate removal. Ultrasonically bonded construction with Luer-Lok® and pressure fitting compatibility maximizes connection reliability across diverse laboratory instrumentation and protocols.

Key Cellulose Acetate Membrane Characteristics

Inherently hydrophilic nature with water affinity enables immediate aqueous sample compatibility without pre-wetting requirements or flow delays
Ultra-low protein binding properties preserve biomolecule concentrations throughout filtration, maintaining sample integrity for downstream HPLC analysis
0.22µm pore configuration delivers reliable bacterial retention while optimizing flow rates for protein-based solutions and biological matrices
Broad chemical compatibility with acids, bases, and diverse solvents accommodates varied analytical sample preparation requirements
Surfactant treatment ensures consistent wettability and reproducible filtration performance across all membrane surfaces

Key Construction Characteristics

Ultrasonically bonded housing eliminates adhesive contamination while delivering superior seal integrity under pressure applications
Female Luer-Lok® inlet with male Luer slip outlet provides universal syringe compatibility and secure connection reliability
Concentric funnel-shaped barrel design increases filtration volume capacity while reducing back pressure during viscous sample processing
Clearly inscribed membrane type identification on barrel ensures proper filter selection and prevents cross-contamination in multi-user environments
Autoclave sterilization compatibility enables pre-cleaning protocols for ultra-trace applications requiring validated sterility assurance

LE-IWT-ES10083 filters achieve outstanding unit-to-unit and lot-to-lot reproducibility, accelerating your analytical workflows while maintaining consistent performance across extended sampling campaigns. Fast flow rate characteristics combined with nitrate-free cellulose acetate construction makes these filters ideal for groundwater monitoring and environmental sample preparation. Superior compatibility with tissue culture media, serum processing, and HPLC mobile phase preparation transforms these filters into versatile analytical tools, delivering reliable sample clarification for even the most challenging proteinaceous matrices while preserving critical analyte concentrations for accurate quantitative analysis.
