      Featuring quantitative ashless cellulose construction delivering exceptional fine particle retention for critical gravimetric analysis applications. This media demonstrates an extremely high retention rate for a cellulose filter media with retention of approximately 2.5 µm. Ashless filter papers are manufactured in refined pulp and acid washed to achieve superior purity standards for demanding analytical procedures requiring precise weight determinations. Key Cellulose Membrane Characteristics
      • Extremely low ash content of <0.01% eliminates interference in gravimetric weight calculations and spectrophotometric analysis
      • 2.5 µm particle retention delivers the finest particle retention of all Whatman cellulose filter papers for critical analytical applications
      • Hydrophilic surface chemistry ensures rapid wetting and consistent flow characteristics across diverse liquid sample matrices
      • 0.170mm thickness provides optimal structural integrity while maintaining fast filtration rates for high-throughput laboratory operations
      • Refined cellulose construction resists clogging from fine precipitates while maintaining excellent clarity for visual inspection procedures
      Key Construction Characteristics
      • 125mm diameter accommodates standard analytical filter funnels and gravimetric analysis equipment for seamless laboratory integration
      • Quantitative grade manufacturing with controlled porosity ensures reproducible retention performance across multiple filtration cycles
      • Acid-washed processing removes trace metal contaminants that could interfere with elemental analysis and atomic absorption procedures
      • 100-piece packaging delivers convenient quantity sizing for routine analytical procedures while maintaining cost-effective inventory management
      • Compatible with both aqueous and organic solvent systems commonly used in analytical chemistry and research applications
      LE-CFP42-125 filters excel in critical gravimetric analysis requiring the highest particle retention standards, including barium sulfate, metastannic acid, and finely precipitated calcium carbonate separations. Outstanding ashless characteristics with <0.01% residue maximize your analytical accuracy by eliminating background interference during ignition procedures. Standard environmental test procedures such as soil sample analysis & the collection of trace elements and radionuclides in air samples benefit from the superior fine particle retention, while liquid food tests for determination of sediments, primary analysis of cements and slurries and sample preparation prior to spectrophotometry achieve enhanced precision through reliable 2.5 µm filtration performance.
