Grade CFP2 Cellulose Filter Paper, Qualitative, 8µm, 55mm, High Absorbency, 100/Pk SKU: LE-CFP2-055

Featuring high-quality cellulose construction delivering enhanced retention and absorbency characteristics for qualitative analytical applications. 8µm pore size provides slightly more retentive performance than Grade 1 filters with correspondingly increased filtration time, optimizing particle separation for medium-flow analytical protocols. Superior absorbent capacity exceeds Grade 1 specifications, maximizing sample retention while maintaining consistent flow characteristics through laboratory filtration processes.

Key Cellulose Membrane Characteristics

190µm thickness with 97g/m² basis weight delivers robust handling integrity during filter installation and sample processing
0.29 psi wet burst strength maintains structural stability under vacuum-assisted filtration conditions
Hydrophilic surface chemistry accelerates wetting and enhances flow rates for aqueous sample matrices
Low ash content below 0.06% minimizes contamination interference in gravimetric and analytical determinations
240s Herzberg filtration speed with 20s/100ml/in² air flow optimizes processing time for routine laboratory applications

Key Construction Characteristics

Standard 55mm diameter circles accommodate universal filter holder configurations and laboratory glassware systems
ASTM E 2187-09 certified performance meets conditioned (26.1 ± 0.5g) and dried (24.7 ± 0.5g) weight requirements
High-grade cotton linter construction ensures consistent pore structure and reliable particle retention characteristics
Medium flow rate specification balances filtration speed with analytical precision for general laboratory separations
Nonsterile format reduces costs while maintaining analytical performance for routine qualitative applications

LE-CFP2-055 filters achieve exceptional versatility across diverse analytical protocols, from plant growth trials requiring nutrient retention capabilities to atmospheric contaminant monitoring and soil testing applications. Enhanced absorbency characteristics transform routine separations by maximizing sample retention, while maintaining the reliable flow rates essential for high-throughput laboratory operations. ASTM E 2187-09 compliance eliminates lot testing requirements, streamlining your analytical workflows and ensuring consistent performance across diverse qualitative filtration applications demanding both enhanced retention and superior absorbent capacity.
