Product Overview
Whatman Grade 2 FF cellulose filter paper is a versatile, medium-retention filter designed for reliable performance in general laboratory filtration tasks. With an 8-micron particle retention rating, it effectively captures fine particulates while maintaining a balanced flow rate, making it suitable for a wide range of qualitative applications. The paper is acid-washed to ensure high purity and minimal extractables, which is critical for sensitive analytical procedures. Its consistent thickness and uniform porosity provide reproducible results, reducing variability in experimental outcomes. The cellulose composition offers excellent chemical compatibility with most aqueous and organic solvents, ensuring broad applicability across different filtration needs. This grade is particularly favored for routine filtration where both clarity and speed are important. The filter paper’s smooth surface minimizes fiber shedding, which helps maintain sample integrity. Available in multiple diameters, it accommodates various funnel sizes and filtration volumes, providing flexibility for different experimental setups. The medium retention capability makes it an ideal choice for applications where finer particles need to be removed without sacrificing filtration speed.
