      Featuring intermediate retention cellulose technology providing 16µm particle retention with optimized flow characteristics for medium-speed quantitative analysis. Ultra-low ash content of <0.01% construction delivers exceptional purity for gravimetric analysis requiring sample combustion, while hydrophilic surface chemistry ensures reliable wetting and uniform filtration across the entire 185mm diameter surface area. Standard thickness of 0.210mm provides mechanical integrity for handling during analytical procedures. Key Cellulose Membrane Characteristics
      • Quantitative ashless construction with <0.007% maximum ash content eliminates residue interference in gravimetric determinations
      • Intermediate 16µm particle retention optimized for medium-speed filtration of precipitates and suspended solids
      • Hydrophilic cellulose matrix provides rapid wetting and uniform sample distribution across filter surface
      • Flow rate positioning intermediate between Grade 40 and 41, delivering twice the speed of Grade 40
      • 0.210mm thickness maintains dimensional stability during extended filtration cycles and sample drying
      Key Construction Characteristics
      • 185mm diameter accommodates standard analytical procedures and funnel configurations for routine laboratory work
      • Tensile strength properties (ASTM D828)1 ensure handling integrity during filter installation and sample processing
      • 100-pack format provides consistent batch quality for extended analytical campaigns and quality control protocols
      • Nonsterile construction suitable for general analytical applications not requiring sterile filtration
      • Compatible with standard laboratory funnels, vacuum filtration apparatus, and gravimetric analysis equipment
      LE-CFP43-185 filters excel in soil analysis, surface water testing, and air pollution monitoring applications requiring subsequent XRF analysis. The quantitative ashless formulation maximizes analytical accuracy by eliminating residue contamination during sample combustion, while the intermediate retention characteristics accelerate processing times compared to finer grades. Proven performance in construction, mining, and steel industry inorganic analysis transforms these filters into reliable media for your critical environmental and materials testing applications demanding both speed and analytical precision.
