Grade CFP542 Quantitative Cellulose Filter Paper, 2-3µm, 150mm, Ashless Wet-Strength, 100/Pk SKU: LE-CFP542-150

Featuring hardened quantitative cellulose technology delivering extremely low ash content of <0.01% for precision gravimetric analysis applications. Very slow flow rates and retention of approximately 2 - 3µm provide exceptional fine particulate capture while ashless and hardened construction with increased wet strength maintains structural integrity during demanding analytical procedures. Ultra-pure cellulose matrix eliminates interference in quantitative determinations requiring validated ash-free performance.

Key Quantitative Cellulose Membrane Characteristics

• Extremely low ash content of <0.01% eliminates gravimetric interference for accurate quantitative analysis results
• Hardened wet-strength construction resists disintegration during extended filtration and sample processing cycles
• Very slow flow rates with 2-3µm retention capture fine precipitates and colloidal particles in analytical procedures
• Entrapping particulate within the random matrix of cellulose fibers provides depth filtration for superior retention efficiency
• Quantitative grade purity manufactured from refined pulp ensures consistent performance across analytical batches

Key Construction Characteristics

• Thickness 0.170mm measured under standardized conditions using TAPPI method T411¹ ensures dimensional consistency
• 150mm diameter accommodates standard analytical filter holders and gravimetric analysis equipment configurations
• Hydrophilic surface chemistry promotes rapid wetting and uniform sample distribution across the filtration area
• Nonsterile format suitable for routine analytical applications where sterility validation is not required
• 100-count packaging provides convenient laboratory supply quantities with protective dispenser box storage

LE-CFP542-150 filters excel in gravimetric analysis procedures where ash-free performance is critical, delivering reliable separation for fine precipitates and analytical sample preparation. Outstanding chemical purity maximizes accuracy in quantitative determinations, while standard environmental test procedures such as soil sample analysis & the collection of trace elements benefit from the exceptional retention characteristics. Liquid food tests for determination of sediments, primary analysis of cements and slurries and sample preparation prior to spectrophotometry applications achieve enhanced precision through the ultra-low ash content and consistent flow characteristics of this quantitative-grade cellulose media.
