Grade CFP6 Cellulose Filter Paper, Qualitative 3-4µm, 320mm, Environmental Analysis, 100/Pk SKU: LE-CFP6-320

Featuring pure alpha-cellulose fiber matrix technology delivering reliable 3-4µm particle retention for environmental monitoring and analytical separations. This qualitative filtration medium combines medium porosity with exceptional flow characteristics, providing efficient clarification of aqueous samples while maintaining superior wet strength during extended processing. The specialized furnish composition results in slightly higher ash content than standard qualitative grades, making this filter paper commonly specified in environmental applications.

Key Cellulose Membrane Characteristics

Pure alpha-cellulose construction provides consistent 3-4µm retention with hydrophilic surface chemistry for superior aqueous sample compatibility
Medium porosity design optimizes flow rates while maintaining reliable particle separation for environmental sample processing
Controlled ash content of 0.22% delivers predictable background levels for analytical procedures requiring moderate purity specifications
Standardized 0.177mm thickness ensures consistent sample loading and uniform filtration characteristics across large-diameter applications
Natural bright white coloration enables visual assessment of filtrate clarity and particle retention during processing

Key Construction Characteristics

320mm diameter accommodates high-volume environmental sampling equipment and large-scale filtration protocols
Robust tensile strength specifications (ASTM D828)¹ maintain structural integrity during vacuum-assisted filtration and sample handling
Depth filtration architecture entraps particulates within the cellulose fiber matrix, providing reliable separation without membrane blocking
Nonsterile format optimized for routine environmental analysis where sterility is not required
Standard 100-count packaging ensures consistent availability for high-throughput laboratory operations

LE-CFP6-320 filters deliver exceptional performance in standard environmental test procedures such as soil sample analysis and the collection of trace elements and radionuclides in air samples. Outstanding chemical compatibility with aqueous solutions accelerates your analytical workflows, while the specialized cellulose composition provides reliable performance for liquid food testing, sediment determination, and sample preparation prior to spectrophotometry. Environmental compliance testing transforms these filters into validated analytical media, offering consistent retention characteristics for your critical monitoring applications demanding both reliable separation and cost-effective processing.
