Grade CFP5 Cellulose Filter Paper, 2.5µm, 90mm, Qualitative, Low Ash <0.05%, 100/Pk SKU: LE-CFP5-090

Featuring high-purity cellulose fiber technology delivering 2.5µm particle retention for precise qualitative analysis applications in environmental science and chemical research. This specialized filter paper excels at filtration of very fine particulate and clarification with applications in environmental sciences and chemical analysis. Ultra-low ash content below 0.05% ensures minimal contamination interference while 0.195mm thickness provides consistent structural integrity during extended filtration processes.

Key Cellulose Membrane Characteristics

Qualitative cellulose construction performs separation by entrapping particulate within the random matrix of cellulose fibers for reliable depth filtration
Retention of approximately 2.5µm particles captures fine sediments while maintaining slow, controlled flow rates
Hydrophilic surface chemistry promotes even liquid distribution and optimal wetting characteristics for aqueous sample processing
Low ash content of <0.05% minimizes analytical interference in gravimetric determinations and trace analysis procedures
Natural fiber composition clarifies liquid samples effectively without introducing synthetic contaminants into your analytical workflow

Key Construction Characteristics

Standard 90mm diameter accommodates common laboratory funnel sizes and standard filtration apparatus configurations
Consistent 0.195mm thickness ensures uniform flow characteristics and reliable filtration performance across the entire surface area
Nonsterile grade optimized for routine laboratory separations where sterility is not required, reducing costs for high-volume applications
100-piece packaging in convenient dispenser box format maintains filter integrity and provides easy bench-top access during use
Widely used in methods requiring the determination and identification of particulate in both liquids and gas for versatile analytical flexibility

LE-CFP5-090 filters achieve exceptional slow flow rates optimized for fine particle retention, ensuring complete separation of suspended solids from your sample matrix. Outstanding performance in general laboratory separation and clarification applications as well as for soil analysis methods makes these filters essential for environmental monitoring, water quality testing, and chemical analysis protocols. The qualitative grade designation transforms these filters into reliable separation media for routine analytical work where precise particle size determination is not critical but consistent clarification performance is essential.
