Grade CFP43 Quantitative Ashless Cellulose Filter Paper, 16µm, 90mm, Cotton Cellulose, 100/Pk SKU: LE-CFP43-090

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 with 15-17 µm retention characteristics optimized for analytical procedures requiring reliable particulate separation. Cotton cellulose construction with ashless finishing ensures contamination-free results while maintaining structural integrity throughout demanding laboratory protocols.

Key Cellulose Membrane Characteristics

• Manufactured from refined pulp and alpha linters providing consistent fiber matrix density for reproducible separations
• Acid washed construction eliminates metallic impurities and organic contaminants that could interfere with quantitative determinations
• Medium flow rate characteristics balance filtration speed with retention efficiency for optimized laboratory productivity
• 16 µm pore structure captures fine particulates while maintaining adequate permeability for liquid and gas phase separations
• Entraps particulate within the random matrix of cellulose fibers within the depth of the media ensuring complete retention throughout filter thickness

Key Construction Characteristics

• Standard 90mm diameter with 0.210mm thickness accommodates most laboratory filtration apparatus and funnel configurations
• 85 g/m² basis weight provides mechanical strength for handling while maintaining optimal porosity characteristics
• Hydrophilic surface chemistry ensures rapid wetting and consistent flow initiation with aqueous solutions and polar solvents
• Cotton cellulose composition delivers chemical compatibility with most acids, bases, and organic solvents used in analytical procedures
• Nonsterile packaging suitable for routine laboratory applications where sterility validation is not required

LE-CFP43-090 filters excel in gravimetric analysis of soil samples, surface water testing procedures and air sample monitoring equipment applications, delivering the precision your analytical protocols demand. Standard environmental test procedures such as soil sample analysis & the collection of trace elements and radionuclides in air samples. Also used in liquid food tests for determination of sediments, primary analysis of cements and slurries and sample preparation prior to spectrophotometry. The ashless formulation transforms these filters into validated reference-grade media, providing performance assurance for your critical quantitative analysis applications requiring both reliable retention and contamination-free results.
