LabExact
Grade CFP42 Quantitative Cellulose Filter Paper, 2.5µm, 185mm, Ashless, High-Retention, 100/Pk SKU: LE-CFP42-185

Featuring quantitative ashless cellulose technology delivering an extremely high retention rate for a cellulose filter media optimized for gravimetric analysis of fine precipitates. A precise 2.5µm pore configuration provides exceptional particle retention while maintaining reliable flow characteristics through 185mm diameter construction. Manufactured from refined pulp with extremely low ash content of <0.01%, delivering validated performance for quantitative analytical procedures requiring maximum purity and accuracy.

Key Cellulose Membrane Characteristics

• Acid washed construction with extremely low ash content <0.01% eliminates contamination in gravimetric determinations
• Uniquely high retention rate makes it ideal for any gravimetric analysis of very fine precipitates including gelatinous samples
• Hydrophilic cellulose matrix provides consistent wetting characteristics for aqueous sample processing
• 2.5µm retention efficiency captures fine particles while optimizing filtration flow rates for analytical procedures
• Quantitative grade construction ensures reproducible results for precision analytical measurements

Key Construction Characteristics

• Standard 185mm diameter accommodates common laboratory filtration equipment and analytical funnel configurations
• 0.170mm thickness provides robust structural integrity during sample processing and handling
• Ashless formulation enables direct ashing procedures without interference from organic binders or contaminants
• Performs separations by entrapping particulate within the random matrix of cellulose fibers throughout the depth of the media
• Non-sterile configuration optimized for general laboratory analytical applications requiring high-purity filtration

LE-CFP42-185 filters deliver consistent performance for standard environmental test procedures such as soil sample analysis & the collection of trace elements and radionuclides in air samples. Outstanding retention characteristics accelerate your analytical workflows when processing samples requiring separation of very fine precipitates. Quantitative ashless construction maximizes your analytical precision for gravimetric determinations, spectrophotometric sample preparation, and quality control applications demanding both exceptional purity and validated performance consistency.
