Grade CFP540 Quantitative Ashless Cellulose Filter Paper, 7-8µm, 185mm, Medium Flow, 100/Pk SKU: LE-CFP540-185

Featuring quantitative ashless cellulose technology delivering superior wet strength and medium flow characteristics for gravimetric analysis applications. Grade CFP540 quantitative cellulose filter media is ashless and hardened with increased wet strength, providing reliable particulate retention of 7 - 8 µm while maintaining dimensional stability throughout analytical procedures. Extremely low ash content of <0.01% ensures minimal interference during gravimetric determinations and sample preparation protocols requiring validated analytical accuracy.

Key Cellulose Membrane Characteristics

• Quantitative grade ashless construction eliminates inorganic residue contamination during ignition procedures
• Hardened cellulose matrix with enhanced wet strength maintains structural integrity under aggressive chemical conditions
• 7-8 µm retention efficiency captures fine particulates while optimizing filtration speed for routine analytical workflows
• Hydrophilic surface chemistry promotes rapid liquid penetration and uniform sample distribution across the filter area
• Medium flow rate characteristics balance filtration speed with retention performance for versatile laboratory applications

Key Construction Characteristics

• Precision 185mm diameter accommodates large sample volumes while fitting standard analytical filtration equipment
• 0.210mm thickness specification provides mechanical strength without compromising flow dynamics or sample clarity
• Acid-washed cellulose construction removes trace metals and ionic contaminants for ultra-clean analytical results
• Compatible with organic solvents, aqueous solutions, and most laboratory reagents for diverse separation applications
• Convenient 100-piece packaging with protective dispenser box maintains filter integrity during storage and handling

LE-CFP540-185 filters achieve exceptional performance in gravimetric analysis, soil extractions, and environmental sample preparation where precise particulate retention and minimal ash interference are critical. Outstanding chemical compatibility with acids, bases, and organic solvents maximizes your analytical flexibility across diverse sample matrices. Whatman 1540-185 equivalent performance transforms these filters into validated reference-grade media, delivering the analytical precision and reproducibility demanded by quantitative laboratory procedures requiring both medium flow rates and ultra-low background contamination.
