Grade CFP542 Cellulose Filter Paper, Quantitative Ashless, 2-3µm, 185mm, Wet-Strength, 100/Pk SKU: LE-CFP542-185

Featuring quantitative ashless cellulose construction delivering exceptional analytical precision for gravimetric applications requiring ultra-low ash contamination. Extremely low ash content of <0.01% combines with retention of approximately 2-3µm to provide reliable fine particulate capture while maintaining analytical purity standards. Hardened construction with increased wet strength ensures structural integrity during extended filtration cycles and aggressive chemical processing applications.

Key Cellulose Matrix Characteristics

• Quantitative ashless grade construction eliminates interference in gravimetric determinations and trace analysis protocols
• 0.170mm thickness optimized for balanced flow rates while maximizing mechanical strength during sample processing
• Hardened wet-strength treatment withstands aggressive solvents and maintains dimensional stability throughout extended filtration procedures
• Fine pore structure captures 2-3µm particles with high efficiency while preventing premature filter clogging in high-volume applications
• Ultra-pure cellulose furnish delivers consistent performance across analytical chemistry, environmental testing, and research laboratory protocols

Key Construction Characteristics

• Hydrophilic surface chemistry promotes rapid wetting and uniform flow distribution across the entire 185mm diameter surface area
• Nonsterile format provides cost-effective solution for routine analytical procedures not requiring sterile processing conditions
• Standard 185mm diameter accommodates large-volume sample processing and universal funnel configurations for laboratory efficiency
• Thickness measured under 4 psi using TAPPI method T411¹ ensures consistent caliper specifications for reproducible filtration performance
• Convenient 100-piece packaging with dispenser box design minimizes contamination risk while streamlining laboratory workflow management

CFP542 filters achieve very slow flow rates optimized for analytical applications requiring maximum retention efficiency, delivering superior performance in quantitative analysis procedures where trace contamination must be eliminated. Outstanding chemical compatibility with most laboratory solvents and reagents maximizes analytical flexibility when processing diverse sample matrices. Ultra-low ash content transforms these filters into validated analytical-grade media, providing performance assurance for critical gravimetric determinations, residue analysis, and precision laboratory applications demanding both exceptional purity and reliable particulate retention accuracy.
