8µm particle retention with medium flow characteristics balances throughput with effective separation performance
Random cellulose fiber matrix provides depth filtration for both coarse and fine particulate entrapment
Hydrophilic surface properties ensure consistent wetting and reliable flow rates with aqueous solutions
Ashless formulation prevents interference with analytical measurements requiring sample combustion or ashing

Key Construction Characteristics

Standard 70mm diameter with 0.200mm thickness accommodates universal filter holder configurations and funnel assemblies
Refined pulp manufacturing process eliminates synthetic binders and additives that could contaminate analytical samples
Medium porosity structure optimizes flow rates while maintaining consistent retention across the filter surface
Robust fiber integrity withstands folding and handling during laboratory procedures without tearing or degradation
Compatible with standard laboratory solvents and maintains structural stability throughout filtration processes

LE-CFP40-070 filters excel in standard environmental test procedures such as soil sample analysis and the collection of trace elements and radionuclides in air samples. Outstanding versatility extends to liquid food tests for determination of sediments, primary analysis of cements and slurries and sample preparation prior to spectrophotometry. The superior ashless characteristics transform these filters into essential media for any analytical workflow requiring combustible filter papers, ensuring your quantitative results maintain the highest accuracy and precision standards.
