Grade CFP3 Qualitative Cellulose Filter Paper, 6µm, 42mm, Slow Flow, High Volume, 100/Pk SKU: LE-CFP3-042

Featuring high-capacity qualitative cellulose fiber technology delivering 6µm particle retention with significantly slower flow rates optimized for high-volume sample processing applications. Double-thickness construction at 0.32mm provides twice the depth filtration capacity of standard grades while maintaining exceptional particle entrapment within the random cellulose fiber matrix. Superior resistance to clogging compared to other qualitative cellulose types enables much higher sample volume usage, maximizing your analytical throughput for demanding laboratory separations.

Key Cellulose Membrane Characteristics

• Approximately 6µm retention delivers precise particulate separation with controlled slow flow characteristics
• Basis weight of 190g/m² with 0.32mm thickness provides enhanced depth filtration capacity
• Very high absorbency levels enable dual functionality as sample conveyance substrate for transfer applications
• Ultra-low ash content of 0.05% minimizes interference in analytical determinations
• Random cellulose fiber matrix entraps particulates within the depth of the media for reliable separation

Key Construction Characteristics

• Hydrophilic surface chemistry ensures rapid wetting and consistent flow initiation across sample types
• 42mm diameter accommodates standard laboratory filter holders and funnel configurations
• Nonsterile presentation optimized for general laboratory and analytical applications
• Enhanced resistance to clogging maintains filtration performance even with high particulate loads
• 100-count packaging in convenient dispenser format reduces contamination and improves laboratory workflow

LE-CFP3-042 filters excel in methods requiring determination and identification of particulate in both liquids and gas samples, delivering reliable performance for your most demanding separation challenges. Natural fiber construction provides effective clarification of liquid samples while the enhanced thickness design prevents premature breakthrough in high-volume applications. Widely specified for general laboratory separation and clarification applications as well as soil analysis methods, these filters transform complex sample matrices into clear, analytically-ready solutions with confidence and reproducibility.
