Product Overview
Whatman Grade 0048 cellulose filter paper is engineered for reliable performance in general laboratory filtration applications. Manufactured from high-purity cellulose fibers, this grade offers a balanced combination of flow rate and particle retention, making it suitable for routine filtration tasks. The 20-25µm particle retention capability ensures efficient separation of fine particulates while maintaining optimal flow characteristics. The medium-speed filtration rate reduces processing time without compromising filtration quality. Each sheet maintains consistent thickness and porosity, providing reproducible results across multiple experiments. The acid-washed treatment enhances chemical compatibility, allowing use with a wide range of aqueous and organic solutions. The smooth surface minimizes fiber shedding, reducing potential sample contamination. This grade is particularly effective for applications requiring moderate retention capabilities where faster flow rates are beneficial. The uniform pore structure ensures even particle distribution during filtration, while the high wet strength prevents tearing during handling. As a standard laboratory consumable, Whatman Grade 0048 filter paper delivers consistent performance across various filtration protocols, making it a dependable choice for routine laboratory operations.
FAQs
1. What is the particle retention range for Whatman Grade 0048 filter paper?
This grade retains particles in the 20-25 micron range, making it suitable for general filtration applications where moderate retention is required.
2. Can this filter paper be used with organic solvents?
The acid-washed treatment provides good chemical compatibility with many organic solvents, though compatibility should be verified for specific applications.
3. How does the flow rate compare to other Whatman grades?
Grade 0048 offers a medium flow rate, faster than high-retention grades but slower than coarse filtration papers, providing a balanced performance.
4. What is the recommended storage method for these filter papers?
Store in a cool, dry environment in the original packaging to maintain cleanliness and prevent moisture absorption that could affect performance.
5. Are there alternative Whatman grades with similar characteristics?
Grade 0047 has comparable properties but with slightly different retention characteristics, while Grade 0044 offers faster flow with lower retention.
