Grade CFP43 Cellulose Filter Paper, Quantitative Ashless, 16µm, 55mm, Medium Flow, 100/Pk SKU: LE-CFP43-055

Featuring quantitative ashless cellulose construction delivering extremely low ash content <0.01% for precise gravimetric analysis applications. Positioned as an intermediate within the quantitative cellulose family, this grade demonstrates medium retention and flow rates optimized for environmental testing protocols. Acid-washed cotton cellulose with 15-17 µm retention ensures reliable particle separation while maintaining optimal flow characteristics for routine analytical procedures.

Key Cellulose Membrane Characteristics

• Manufactured from refined pulp and linters with acid washing treatment eliminating organic contaminants
• Extremely low ash content <0.01% validates quantitative analytical accuracy for gravimetric determinations
• 15-17 µm particle retention provides intermediate filtration efficiency between coarse and fine grade papers
• 85 g/m² basis weight with 0.210mm thickness ensures mechanical strength during filtration procedures
• Cotton cellulose fiber matrix traps particulates within depth media structure maximizing retention capacity

Key Construction Characteristics

• Standard 55mm diameter accommodates common filter funnel configurations and laboratory equipment setups
• Medium flow rate characteristics balance filtration speed with particle retention efficiency
• Hydrophilic surface chemistry promotes even wetting and consistent flow patterns during aqueous sample processing
• Non-sterile format reduces costs while maintaining analytical performance for routine laboratory applications
• 100-count packaging provides convenient laboratory supply quantities with batch consistency tracking

LE-CFP43-055 filters excel in gravimetric analysis of soil samples, surface water testing procedures and air sample monitoring equipment applications requiring validated particle separation. Standard environmental test procedures including soil sample analysis, collection of trace elements and radionuclides in air samples, liquid food testing for sediment determination, and sample preparation prior to spectrophotometry benefit from the consistent medium-flow performance characteristics. Optimized 16µm retention delivers reliable processing of suspended solids, precipitates, and environmental particulates demanding both analytical accuracy and procedural efficiency in your quantitative laboratory workflows.
