Product Overview
Whatman Grade 2294 cellulose filter paper is engineered for demanding laboratory applications requiring superior wet strength and chemical resistance. Composed of high-purity cellulose fibers, this grade maintains structural integrity even under aggressive filtration conditions, ensuring consistent particle retention without fiber shedding. The medium retention rate (8-12 μm) balances flow rate and efficiency, making it suitable for both coarse and fine particulate separation. Its acid- and alkali-resistant properties allow safe use with a wide range of solvents and reagents, while the uniform thickness guarantees reproducible results. The paper?s inherent purity minimizes extractables, reducing interference in sensitive analyses. Available in multiple diameters, it adapts to various filtration setups, from standard funnels to specialized apparatus. The smooth surface facilitates easy sample recovery, and the pre-cut circles eliminate preparation time. Designed for repeated use in critical protocols, Grade 2294 delivers reliability across multiple filtration cycles without compromising performance.
FAQs
1. What is the particle retention range for Whatman Grade 2294 filter paper?
This grade retains particles in the 8-12 ?m range, providing a balance between flow rate and filtration efficiency for general lab applications.
2. Can this filter paper be used with organic solvents like acetone or methanol?
Yes, Grade 2294 is chemically resistant to most organic solvents, including acetone, methanol, and mild acids, making it versatile for various filtration needs.
3. How does the wet strength of Grade 2294 compare to standard filter papers?
The high wet strength of Grade 2294 exceeds that of standard cellulose papers, allowing it to withstand prolonged filtration without tearing or deforming.
4. Is this filter paper suitable for vacuum filtration setups?
Absolutely, its robust structure makes it ideal for vacuum-assisted filtration, maintaining integrity even under negative pressure conditions.
5. What alternatives exist if I need finer particle retention than 8 ?m?
For finer filtration, consider Whatman Grade 42 (2.5 ?m) or Grade 541 (20-25 ?m for faster flow with slightly coarser retention).
