      Featuring ashless quantitative cellulose filtration technology delivering exceptional precision for gravimetric analysis applications. Grade CFP540 quantitative cellulose filter media is ashless and hardened with increased wet strength, providing superior handling integrity during complex analytical procedures. Medium flow rates and retention of approximately 7 - 8 um optimize sample processing while maintaining precise particulate separation for demanding laboratory protocols.
      Key Quantitative Cellulose Membrane Characteristics
      • Ashless construction with extremely low ash content of <0.01% eliminates interference in gravimetric determinations and trace analysis
      • Hardened wet strength technology maintains structural integrity during extended filtration cycles and aggressive sample processing
      • 7.0-8.0µm retention efficiency captures medium-fine particulates while optimizing flow rates for high-volume applications
      • Hydrophilic cellulose matrix delivers consistent wetting characteristics for aqueous sample processing and liquid clarification
      • Acid-washed purification removes contaminating metals and organic residues ensuring analytical accuracy
      Key Construction Characteristics
      • Premium 150mm diameter accommodates standard laboratory filter holders and high-volume sample processing requirements
      • Thickness 0.210mm provides optimal balance of mechanical strength and filtration performance for quantitative applications
      • Refined alpha-cellulose construction from high-purity cotton linters delivers consistent porosity and particle retention
      • Standard flat-sheet format compatible with vacuum filtration systems, gravity funnels, and pressure filtration apparatus
      • Thickness measured under 4 psi using TAPPI method T4111 ensures dimensional consistency across production batches
      LE-CFP540-150 filters excel in standard environmental test procedures such as soil sample analysis & the collection of trace elements and radionuclides in air samples, accelerating your analytical workflows while maintaining measurement precision. Outstanding chemical resistance and dimensional stability maximize compatibility with diverse solvents and sample matrices encountered in liquid food tests for determination of sediments, primary analysis of cements and slurries and sample preparation prior to spectrophotometry. Ultra-low ash content transforms these filters into reference-grade media for critical gravimetric analysis, providing confidence in your most demanding quantitative determinations requiring both precise particle retention and contamination-free results.
