Grade CFP541 Quantitative Cellulose Filter Paper, 23µm, 185mm, Wet-Strength, Ashless, 100/Pk SKU: LE-CFP541-185

Featuring hardened wet-strength cellulose construction delivering fast flow rates and retention of approximately 21 - 23 µm for demanding quantitative analytical applications. Grade CFP541 quantitative cellulose filter media is ashless and hardened with increased wet strength, providing exceptional handling integrity during routine gravimetric analysis and multi-stage filtration protocols. Extremely low ash content of <0.01% ensures contamination-free results while maintaining structural stability in both liquid and gas filtration applications.

• Hardened wet-strength construction resists tearing and maintains dimensional stability during extended liquid contact and washing procedures
• 23µm nominal retention delivers precise particulate capture while optimizing flow rates for high-throughput analytical processing
• Hydrophilic surface chemistry promotes rapid liquid penetration and uniform wetting for consistent filtration performance
• Ultra-low ash content below 0.01% eliminates interference in gravimetric determinations and trace element analysis applications
• Quantitative grade purity ensures reliable results in critical analytical procedures requiring validated filtration media

• 0.200mm thickness measured under 4 psi using TAPPI T411¹ provides optimal balance of strength and filtration efficiency
• 185mm diameter accommodates standard laboratory filter funnels and supports high-volume sample processing requirements
• Ashless formulation withstands ignition at 900°C without residue formation, enabling accurate weight determinations in analytical protocols
• Nonsterile packaging in convenient 100-piece dispenser boxes maintains product integrity while facilitating easy laboratory bench storage
• Cellulose fiber matrix construction delivers 98% retention efficiency for targeted particle size ranges in liquid separation applications

LE-CFP541-185 filters achieve fast flow characteristics optimized for routine laboratory separations, accelerating your analytical cycles while maintaining precision in quantitative determinations. Outstanding wet-strength properties maximize your operational flexibility when processing aqueous samples and conducting washing procedures requiring multiple liquid contacts. Quantitative grade specifications transform these filters into validated analytical media, providing performance assurance for your critical gravimetric analysis, environmental sample preparation, and general laboratory filtration applications demanding both precision and reliability.
