LabExact
Grade CFP4 Cellulose Filter Paper, Qualitative, 25µm, 110mm, Fast Flow, 100/Pk SKU: LE-CFP4-110

Featuring qualitative cellulose fiber technology delivering the fastest flow rate demonstrated by any qualitative cellulose filter media with approximately 25µm particle retention. Optimized for multi-stage filtration processes where rapid throughput maximizes efficiency without compromising separation performance. Standard basis weight per meter² at 8% moisture content with thickness measured under 4 psi using TAPPI method T411¹ ensures consistent handling characteristics and reliable installation in standard laboratory equipment.

Key Cellulose Membrane Characteristics

• Ultra-fast flow rates accelerate sample processing while maintaining 25µm particle retention precision
• Natural cellulose fiber matrix performs separation by entrapping particulate within random fiber depth
• Bright white construction optimizes clarity for visual assessment and photometric analysis applications
• Low ash content below 0.05% minimizes interference in gravimetric determinations
• Superior purity manufacturing process delivers contamination-free results for analytical applications

Key Construction Characteristics

• Standardized basis weight specification at 8% moisture content ensures consistent filtration performance
• TAPPI T411¹ thickness measurement protocol validates dimensional stability under laboratory conditions
• 110mm diameter accommodates standard laboratory filter holders and vacuum filtration equipment
• Hydrophilic surface chemistry enhances wetting characteristics for aqueous sample processing
• Nonsterile construction optimized for general laboratory separation and clarification procedures

LE-CFP4-110 filters excel in organic extractions and biological fluid separation processes where rapid sample throughput accelerates analytical workflows. Frequently specified in air monitoring applications where fine particulate entrapment is not required, these filters maximize airflow while capturing target analytes. Environmental testing procedures including soil sample analysis and trace element collection benefit from the ultra-fast flow characteristics, delivering efficient sample preparation for downstream analytical methods requiring validated filtration protocols.
