Product Overview
Whatman Grade 1573 FF is a high-performance cellulose filter paper engineered for rapid filtration without compromising particle retention. Its medium retention capacity (11-16 ?m) makes it versatile for a wide range of laboratory applications where both speed and precision are critical. The paper?s unique composition ensures high wet strength, preventing tearing even under demanding filtration conditions. Unlike standard filter papers, the 1573 FF grade is chemically resistant to mild acids and alkalis, ensuring reliable performance in diverse solvent environments. The fast flow rate significantly reduces filtration time, improving workflow efficiency in high-volume settings. Its consistent thickness and porosity provide uniform filtration, minimizing variability in experimental results. The paper is manufactured under stringent quality controls, guaranteeing low extractables and minimal background interference, which is essential for sensitive analytical procedures. Whether used in gravity or vacuum filtration setups, this filter paper maintains structural integrity, making it a dependable choice for routine and specialized filtration tasks. The natural cellulose fibers are free from binders or additives, ensuring purity and compatibility with most laboratory protocols.
