Product Overview
Whatman Grade 589/2 White Ribbon Filter Paper is a high-purity, medium-speed qualitative filter designed for reliable performance in laboratory filtration tasks. Manufactured from pure cotton linters, this filter paper undergoes rigorous quality control to ensure consistency in particle retention and flow rate. The 589/2 grade features a medium retention capacity (approximately 4-7 ?m), making it suitable for a wide range of applications where moderate particle separation is required. Its white ribbon finish indicates high alpha-cellulose content, ensuring minimal extractables and superior chemical resistance. The uniform surface texture promotes even particle distribution, while the controlled thickness provides optimal strength during wet handling. This grade is particularly valued for its balance between filtration speed and retention efficiency, delivering reproducible results in both routine and critical procedures. The filter paper is compatible with most common laboratory solvents and maintains structural integrity across a broad pH range. Each pack is individually wrapped to preserve cleanliness and prevent contamination during storage.
