Product Overview
Whatman Grade 54 cellulose filter paper is a versatile, medium-retention filter designed for general laboratory filtration tasks. Engineered with a particle retention range of 7-12 μm, this acid-washed filter paper ensures high purity and consistent performance across various applications. Its robust wet strength makes it suitable for both gravity and pressure filtration, providing reliable results even under demanding conditions. The cellulose composition offers excellent chemical compatibility, allowing for use with a wide range of solvents and aqueous solutions. Each sheet maintains uniform thickness and porosity, minimizing clogging and ensuring efficient flow rates. The filter paper undergoes rigorous quality control to guarantee low extractables, making it ideal for applications requiring minimal interference. Its smooth surface texture facilitates easy particle capture while maintaining structural integrity during prolonged use. The medium retention capability balances filtration efficiency with flow rate, making it a preferred choice for routine laboratory procedures where precision and reproducibility are critical.
FAQs
1. What is the particle retention range of Whatman Grade 54 filter paper?
This filter paper has a particle retention range of 7-12 ?m, making it suitable for medium filtration applications where finer particles need to be captured without sacrificing flow rate.
2. Can this filter paper be used with organic solvents?
Yes, Whatman Grade 54 is compatible with most organic solvents and aqueous solutions due to its cellulose composition, though compatibility should always be verified for specific solvent mixtures.
3. How does the wet strength of Grade 54 compare to other Whatman grades?
Grade 54 offers superior wet strength compared to many standard filter papers, allowing it to maintain structural integrity during pressure filtration or when handling viscous liquids.
4. Is this filter paper pre-treated or acid-washed?
The filter paper is acid-washed during manufacturing to reduce extractables and improve chemical purity, making it suitable for sensitive applications.
5. What is the typical flow rate for this grade of filter paper?
The flow rate depends on the application, but Grade 54 is designed to provide a balanced flow rate for medium-retention filtration, ensuring efficient processing without premature clogging.
