Grade CFP542 Cellulose Filter Paper, Quantitative Ashless, 2-3µm, 320mm, Wet-Strength, 100/Pk SKU: LE-CFP542-320

Featuring hardened wet-strength cellulose construction delivering precision filtration for quantitative analysis applications. Ashless and hardened with increased wet strength, this 2-3µm retention media provides very slow flow rates optimized for gravimetric procedures requiring exceptional precision. Extremely low ash content of <0.01% ensures minimal interference in analytical determinations while maintaining dimensional stability throughout extended filtering operations.

Key Cellulose Membrane Characteristics

• Quantitative ashless construction eliminates residual contamination during high-temperature incineration procedures
• Hardened wet-strength treatment maintains structural integrity when saturated with aqueous solutions or aggressive solvents
• 0.170mm thickness specification provides consistent flow resistance and particle retention across the filter surface
• Hydrophilic cellulose matrix enables immediate wetting and uniform solution distribution for reproducible filtration
• 98% retention efficiency captures fine particulates while maintaining optimal permeability for laboratory throughput

Key Construction Characteristics

• High-quality refined pulp and alpha linters construction delivers superior chemical purity for analytical applications
• 320mm diameter accommodates large-volume sample processing and high-capacity laboratory filtration systems
• Ash content determined by exposure at 900°C in muffle furnace validates quantitative grade specifications
• Random matrix cellulose fiber structure performs depth filtration by entrapping particles throughout the media thickness
• 100-filter dispenser packaging protects media from debris and damage while enabling convenient bench storage

Grade CFP542 filters excel in gravimetric analysis procedures and deliver reliable performance when preparing samples for instrumentation testing. The hardened wet-strength formulation withstands aggressive laboratory conditions while maintaining filtration consistency throughout your analytical protocols. Environmental test procedures including soil sample analysis and trace element collection benefit from this media's exceptional retention characteristics, accelerating your quantitative determinations while ensuring analytical accuracy for critical laboratory applications.
