Grade CFP44 Quantitative Ashless Cellulose Filter Paper, 3µm, 110mm, Slow Flow, 100/Pk SKU: LE-CFP44-110

Featuring quantitative ashless cellulose technology delivering exceptional 3µm particle retention for precise gravimetric analysis applications. Very similar to CFP42 but demonstrating a slightly wider retention rate within a similar flow rate, this specialized filter media achieves extremely low ash content <0.01% through advanced acid washing processes. Cotton/ashless furnish construction with 85 g/m² basis weight provides reliable separation performance for demanding analytical procedures requiring ultra-pure filtration media.

Key Cellulose Membrane Characteristics

Manufactured from refined pulp and alpha linters with acid washing treatment eliminates organic contamination for gravimetric accuracy
1.5-3.5 µm retention range with slow flow characteristics optimizes separation efficiency for fine precipitate analysis
Extremely low ash content of <0.01% ensures minimal interference in quantitative determinations and sample purity
0.165mm thickness specification delivers consistent filtration depth while maintaining structural integrity during use
98% efficiency particulate retention in liquid applications provides reliable separation performance for critical analytical procedures

Key Construction Characteristics

Hydrophilic cellulose matrix ensures rapid wetting and optimal flow characteristics for aqueous sample processing
110mm diameter configuration accommodates standard laboratory filtration equipment and funnel assemblies
85 g/m² basis weight construction balances filtration efficiency with mechanical strength for reliable handling
Quantitative grade purity specifications meet requirements for trace analysis and precision gravimetric determinations
Nonsterile packaging in convenient 100-piece quantities supports high-volume laboratory operations and inventory management

LE-CFP44-110 filters excel in analysis of samples requiring separation of very fine precipitates, delivering validated performance for environmental testing, chemical analysis, and quality control applications. Standard environmental test procedures such as soil sample analysis & the collection of trace elements and radionuclides in air samples benefit from the precision retention characteristics, while liquid food tests for determination of sediments, primary analysis of cements and slurries and sample preparation prior to spectrophotometry achieve enhanced accuracy through the ultra-low ash content and consistent pore structure of this quantitative cellulose media.
