Product Overview
Whatman Grade 1450CV cellulose filter paper is engineered for consistent performance in laboratory filtration applications requiring medium particle retention. Manufactured from high-purity cellulose fibers, this grade delivers superior wet strength and chemical resistance, ensuring reliable results even under demanding conditions. The 1450CV grade is specifically designed to balance flow rate and retention efficiency, making it suitable for a wide range of filtration tasks where precision is critical. Its uniform pore structure minimizes clogging while maintaining high loading capacity, reducing the need for frequent filter changes. The paper’s inherent purity ensures minimal extractables, preventing contamination of sensitive samples. Whether used for routine filtration or specialized processes, Whatman 1450CV provides consistent performance with lot-to-lot reproducibility. Its compatibility with common organic solvents and aqueous solutions further enhances its versatility in diverse laboratory workflows. The 90mm diameter format offers practical handling for standard filtration setups, while the pack of 50 ensures cost-effective supply for frequent use.
FAQs
1. What is the particle retention range for Whatman 1450CV filter paper?
This grade typically retains particles in the 8-12 micron range, making it suitable for medium-fine filtration applications where both flow rate and retention are important.
2. Can this filter paper be used with acidic or alkaline solutions?
The cellulose composition provides good chemical resistance to mild acids and bases, though prolonged exposure to strong reagents may affect performance. Always verify compatibility for specific applications.
3. How does the wet strength of 1450CV compare to standard filter papers?
Whatman 1450CV is reinforced to maintain structural integrity when wet, offering significantly higher wet strength than untreated cellulose papers, which reduces tearing during filtration.
4. What alternatives exist for finer or coarser filtration needs?
For finer retention, consider Whatman Grade 42 (2.5µm) or Grade 5 (2.5µm with higher flow). For coarser applications, Grade 1 (11µm) or Grade 4 (20-25µm) may be more appropriate.
5. What are the recommended storage conditions for this filter paper?
Store in a cool, dry environment away from direct sunlight and chemical vapors. Keep the original packaging sealed when not in use to prevent moisture absorption and contamination.
