Grade CFP43 Quantitative Ashless Cellulose Filter Paper, 16µm, 110mm, Medium Flow - 100/pk SKU: LE-CFP43-110

Featuring refined cotton cellulose construction with quantitative ashless technology delivering exceptional purity for gravimetric analysis applications. Positioned as an intermediate within the quantitative cellulose family, this grade demonstrates medium retention and flow rates optimized for soil sample testing, surface water analysis, and air monitoring protocols. Acid-washed processing achieves extremely low ash content <0.01% ensuring contamination-free results in critical analytical procedures.

Key Cellulose Membrane Characteristics

Cotton fiber furnish with ashless finish provides 15-17 µm retention for precise particulate separation in quantitative analysis
Ultra-low ash content <0.01% eliminates interference in gravimetric determinations and trace element analysis
Random matrix cellulose fiber construction entraps particulate within the depth of the media maximizing retention efficiency
Medium flow rate characteristics balance filtration speed with thorough particle capture for optimal analytical throughput
Hydrophilic surface chemistry ensures complete wetting and consistent flow patterns during aqueous sample processing

Key Construction Characteristics

Standard 110mm diameter with 0.210mm thickness accommodates conventional filter funnels and analytical apparatus
Basis weight of 85 g/m² delivers mechanical strength while maintaining efficient filtration performance
Manufactured from refined pulp and alpha linters with acid washing treatment ensures analytical grade purity
Pack of 100 filters provides convenient inventory for routine laboratory operations and batch processing
Non-sterile format ready for immediate use in environmental, food, and industrial testing applications

LE-CFP43-110 filters excel in gravimetric analysis of soil samples, surface water testing procedures and air sample monitoring equipment applications requiring validated analytical performance. Standard environmental test procedures including soil sample analysis, collection of trace elements and radionuclides in air samples, liquid food tests for sediment determination, and sample preparation prior to spectrophotometry benefit from the consistent medium retention characteristics. Equivalent performance to Whatman 1443-110 and Sartorius FT-3-101-110 ensures seamless method compatibility while delivering reliable separation efficiency for your most demanding quantitative analytical protocols.
