Key Cellulose Membrane Characteristics

Natural cellulose fiber construction performs separation by entrapping particulate within the random matrix of cellulose fibers within the depth of the media
Exceptionally fast flow rates and loose retention characteristics make this grade ideal for initial separation of gelatinous precipitates
Acid-washed manufacturing process delivers extremely low ash content less than 0.01% for analytical precision
Hydrophilic surface properties enable effective clarification of liquid samples and aqueous solutions
Optimized porosity structure functions effectively as the first media in multi-stage filtration processes

Key Construction Characteristics

Standard 185mm diameter accommodates most laboratory filter funnel configurations and sample processing equipment
Basis weight of 85 g/m² with 0.220mm thickness provides structural integrity during sample filtration
Manufactured from refined pulp and alpha linters ensuring consistent performance and analytical reproducibility
Nonsterile format suitable for routine laboratory separations and general analytical applications
Chemical compatibility enables use in organic extractions and biological fluid separation processes

LE-CFP41-185 filters deliver optimized performance for applications requiring rapid sample throughput while maintaining effective particulate retention for gelatinous materials and challenging sample matrices. Outstanding versatility makes these filters widely used for general laboratory separation and clarification applications as well as for soil analysis methods. The fast flow characteristics and loose retention properties make these filters often specified in air monitoring applications where the entrapment of fine particulate is not required, transforming your sample preparation workflows with reliable performance for preliminary filtration and sample clarification procedures demanding both speed and analytical integrity.
