Product Overview

Whatman Grade 1573 cellulose filter paper is engineered for reliable performance in routine laboratory filtration tasks. Constructed from high-purity cellulose fibers, this medium-speed filter paper delivers consistent particle retention while maintaining an optimal flow rate for efficient processing. The uniform thickness and smooth surface minimize clogging, ensuring reproducible results across applications. Its balanced porosity makes it particularly suitable for qualitative analysis where moderate retention of fine particles is required without sacrificing filtration speed. The paper’s inherent wet strength allows for handling even when saturated, while its chemical compatibility with most aqueous and organic solvents expands its utility in diverse laboratory protocols. Available in multiple diameters and roll formats, this grade provides flexibility for various filtration setups. The acid-washed treatment reduces extractable contaminants, making it appropriate for sensitive applications. Whether used in gravity or vacuum filtration systems, Whatman? Grade 1573 maintains its structural integrity throughout the filtration process, delivering dependable performance for critical laboratory procedures.

FAQs
