      Featuring quantitative cellulose fiber technology delivering exceptional particle retention for critical gravimetric analysis applications. Grade CFP44 demonstrates a slightly wider retention rate within similar flow characteristics compared to CFP42, making it ideal for separating very fine precipitates. Ultra-low ash content below 0.01% ensures accurate gravimetric determinations while 0.165mm thickness provides optimal structural integrity for laboratory filtration protocols. Key Cellulose Membrane Characteristics
      • Manufactured from refined pulp and alpha linters delivering exceptional purity for quantitative analysis procedures
      • Acid-washed construction maintains extremely low ash content below 0.01% for precise weight measurements
      • 3µm particle retention capability captures fine precipitates with consistent analytical performance
      • Hydrophilic surface chemistry enhances wetting characteristics and flow consistency during filtration operations
      • Optimized for gravimetric analysis procedures requiring validated separation of trace-level particulates
      Key Construction Characteristics
      • 125mm diameter accommodates standard laboratory funnel configurations and sample volumes up to moderate capacity
      • Random cellulose fiber matrix performs depth filtration by trapping particulates throughout media structure
      • Acid-washing process removes trace metals and organic contaminants ensuring analytical-grade purity
      • 0.165mm thickness provides handling strength during folding, installation, and sample transfer procedures
      • Non-sterile packaging optimizes cost-effectiveness for routine analytical laboratory applications
      CFP44 filters achieve reliable ignition performance at 800°C, leaving ash residue below 0.01% for accurate gravimetric determinations. Ultra-high purity construction supports precise analysis in applications sensitive to background contamination, accelerating your analytical workflows when processing samples requiring separation of very fine precipitates. Ideal performance characteristics for critical analytical filtration procedures transform these filters into validated reference-grade media, providing consistent results for your soil analysis, cement testing, and spectrophotometric sample preparation applications demanding both exceptional purity and reliable particle retention capabilities.
