Grade CFP5 Qualitative Cellulose Filter Paper, 2.5µm Retention, 240mm, Slow Flow, 100/Pk SKU: LE-CFP5-240

Featuring high-quality cellulose fiber construction delivering precise 2.5µm particle retention for analytical laboratory applications requiring exceptional clarification performance. Grade CFP5 is a qualitative filter for filtration of very fine particulate and clarification with applications in environmental sciences and chemical analysis. Qualitative cellulose filter papers perform separation by entrapping particulate within the random matrix of cellulose fibers within the depth of the media. Ultra-low ash content of less than 0.05% ensures minimal interference in gravimetric procedures while maintaining optimal sample purity for critical chemical determinations.

Key Cellulose Membrane Characteristics

Low ash content of <0.05% delivers contamination-free results for precise analytical measurements and quantitative procedures
Natural cellulose fiber matrix provides reliable particle entrapment through depth filtration mechanics for consistent separation performance
Retention of approximately 2.5µm captures very fine particulates while maintaining slow, controlled flow rates for thorough filtration
Hydrophilic surface chemistry ensures rapid wetting and optimal liquid penetration for efficient sample processing
Uniform porosity distribution throughout 0.195mm thickness maintains consistent filtration characteristics across the entire filter surface
