Product Overview
Whatman Grade 520B FF is a premium cellulose filter paper engineered for fast flow rates and reliable particle retention in laboratory applications. Made from high-purity, acid-free cellulose, this grade ensures minimal extractables, making it suitable for sensitive filtration tasks where chemical interference must be avoided. The fast-flow design allows for efficient processing of large sample volumes without compromising filtration quality. Its coarse particle retention capability makes it ideal for pre-filtration or when working with samples containing high sediment loads. The paper?s consistent thickness and uniform pore structure provide reproducible results, reducing variability in experimental outcomes. Durable yet flexible, it resists tearing during handling and maintains structural integrity even under moderate pressure. Whether used in gravity or vacuum filtration setups, Whatman 520B FF delivers consistent performance, making it a staple in research labs, educational institutions, and industrial quality control environments. Its compatibility with a wide range of solvents and aqueous solutions further enhances its versatility, ensuring adaptability across diverse filtration protocols.
FAQs
1. What is the particle retention range for Whatman Grade 520B FF filter paper?
This grade typically retains particles larger than 8-12 microns, making it suitable for coarse filtration applications where finer particles are not a concern.
2. Can this filter paper be used with organic solvents?
Yes, Whatman Grade 520B FF is compatible with most organic solvents, though prolonged exposure to highly aggressive solvents may affect its structural integrity.
3. How does the fast-flow property benefit filtration processes?
The fast-flow design reduces filtration time significantly, allowing for quicker processing of large sample volumes without clogging, which is particularly useful in high-throughput labs.
4. Is this filter paper autoclavable for sterile applications?
While it can withstand standard autoclaving conditions, repeated sterilization cycles may degrade the cellulose fibers over time, so single-use is recommended for critical sterile applications.
5. What alternatives exist for finer particle retention?
For finer filtration, consider Whatman Grade 1 or Grade 42, which offer retention down to 2-3 microns, though with slower flow rates compared to 520B FF.
