Grade CFP4 Qualitative Cellulose Filter Paper, 25µm, 90mm, Fast Flow, 100/Pk SKU: LE-CFP4-090

Featuring high-speed cellulose filtration technology delivering the fastest flow rate demonstrated by any of the qualitative cellulose filter media with a low retention rate of approximately 25µm. This qualitative-grade filter paper provides exceptional throughput for high-volume sample processing while maintaining consistent particulate separation in multi-stage filtration protocols. Very commonly used as the first media in a multi-stage filtration process, optimizing your laboratory workflow through rapid sample preparation and reliable clarification performance.

Key Cellulose Fiber Characteristics

Superior flow rate performance maximizes sample throughput in time-critical analytical procedures
Ash content below 0.05% ensures minimal interference in subsequent analytical determinations
25µm retention efficiently removes coarse particulates while preserving sample volume and processing speed
Hydrophilic cellulose construction provides excellent wetting characteristics for aqueous and organic solvents
Consistent bright white appearance enables visual assessment and photometric measurement applications

Key Construction Characteristics

90mm diameter accommodates standard laboratory filter funnels and vacuum filtration equipment
Qualitative grade construction withstands routine handling while maintaining structural integrity during filtration
Natural cellulose fiber matrix performs depth filtration through particle entrapment within the media structure
Nonsterile format ready for immediate use in routine laboratory separation applications
100-piece packaging provides convenient bulk quantities for high-volume analytical laboratories

LE-CFP4-090 filters accelerate your sample preparation workflows through exceptional flow characteristics optimized for preliminary filtration steps, ideally suited for use in organic extractions and biological fluid separation processes. Outstanding compatibility with both aqueous and organic solvents maximizes your analytical flexibility when processing diverse sample matrices requiring rapid clarification. Often specified in air monitoring applications where the entrapment of fine particulate is not required, these filters deliver reliable performance for environmental sampling protocols demanding high sample volumes and accelerated processing cycles.
