Product Overview
Whatman Grade 597 FF cellulose filter paper is engineered for high-performance filtration in demanding laboratory environments. Made from 100% pure cellulose, this filter paper undergoes rigorous acid washing to eliminate impurities, ensuring minimal interference with analytical results. The fast flow rate of Grade 597 FF makes it particularly suitable for applications requiring quick processing without compromising retention efficiency. Its uniform porosity and consistent thickness provide reliable particle retention, making it a preferred choice for gravimetric analysis, air monitoring, and general filtration tasks. The paper?s inherent strength and durability prevent tearing or fiber shedding during use, even under high-pressure conditions. Whether used in qualitative or quantitative analysis, this filter paper delivers consistent performance, reducing the need for repeat testing. The absence of binders or additives further enhances its chemical compatibility, allowing it to be used with a wide range of solvents and reagents. With its balanced combination of speed, retention, and purity, Whatman Grade 597 FF is a versatile solution for laboratories prioritizing accuracy and efficiency in their filtration processes.
FAQs
1. What is the flow rate of Whatman Grade 597 FF filter paper?
Whatman Grade 597 FF is classified as a fast-flow filter paper, designed to provide rapid filtration while maintaining effective particle retention for most laboratory applications.
2. Is this filter paper compatible with organic solvents?
Yes, the pure cellulose composition of Grade 597 FF makes it compatible with a wide range of organic solvents, though prolonged exposure to aggressive solvents may affect its structural integrity.
3. How does the acid-washing process benefit filtration?
The acid-washing process removes trace metals and other impurities from the cellulose fibers, reducing background interference in analytical procedures and improving result accuracy.
4. Can this filter paper be used for sterile filtration?
While Grade 597 FF is not sterilized, it can be autoclaved prior to use for applications requiring sterile conditions, provided the autoclaving parameters are suitable for cellulose materials.
5. What is the typical ash content of this filter paper?
The ash content of Whatman Grade 597 FF is extremely low, typically less than 0.01%, making it ideal for applications where residual ash could impact analytical outcomes.
