Grade CFP43 Cellulose Filter Paper, Quantitative Ashless, 16µm, 70mm, Medium Flow, 100/Pk SKU: LE-CFP43-070

Featuring quantitative cellulose technology delivering intermediate retention and flow characteristics optimized for gravimetric analysis and environmental testing applications. Positioned as an intermediate within the quantitative cellulose family, this grade demonstrates medium retention and flow rates. Cotton cellulose construction with ashless finish provides 15-17 µm retention while maintaining exceptional purity for accurate analytical determinations.

Key Cellulose Membrane Characteristics

Acid washed construction delivers extremely low ash content <0.01% eliminating interference in gravimetric procedures
85 g/m² basis weight with 0.210mm thickness provides optimal mechanical strength for handling and filtration integrity
16 µm particle retention captures fine precipitates while maintaining medium flow rates for efficient processing
Refined pulp manufacturing ensures consistent fiber matrix and reproducible analytical results
Hydrophilic cotton cellulose surface promotes rapid wetting and uniform liquid distribution throughout the filtration process

Key Construction Characteristics

Standard 70mm diameter accommodates common laboratory filtration equipment and sample volumes
Medium flow rate characteristics balance filtration speed with retention efficiency for routine analytical procedures
Non-sterile configuration optimized for general laboratory quantitative analysis applications
Ashless grade construction supports accurate gravimetric determinations without residual contamination
Cotton furnish provides excellent chemical compatibility with most aqueous and organic solvents

LE-CFP43-070 filters excel in standard environmental test procedures such as soil sample analysis and collection of trace elements in air samples. The balanced retention and flow characteristics make these filters ideal for liquid food tests for determination of sediments, primary analysis of cements and slurries and sample preparation prior to spectrophotometry. Superior ashless purity with <0.01% residue transforms your gravimetric analysis workflows, providing reliable quantitative results for environmental monitoring, materials testing, and quality control applications demanding both precision and analytical accuracy.
