Product Overview
Whatman Grade 589/1 FF Black Ribbon Filter Paper is engineered for demanding laboratory applications where precision and reliability are non-negotiable. This ashless, high-purity filter paper is crafted from 100% cotton linters, ensuring minimal background interference and consistent performance in gravimetric analysis, air pollution monitoring, and particulate collection. The black ribbon format enhances visibility of fine particles, making it indispensable for qualitative and quantitative filtration tasks. Its robust chemical resistance allows compatibility with a wide range of solvents and reagents, while the uniform pore structure guarantees efficient retention of sub-micron particles. The 150mm diameter provides ample surface area for high-volume sampling, and the pack of 100 ensures cost-effective bulk usage. Designed to meet stringent ISO 9001 standards, this filter paper delivers repeatable results in critical research and industrial settings where accuracy is paramount. The absence of binders or additives eliminates potential contamination risks, making it a trusted choice for sensitive analytical procedures.
FAQs
1. What is the particle retention capacity of Whatman Grade 589/1 FF filter paper?
This grade retains particles down to 3 micrometers with high efficiency, making it suitable for fine particulate collection and gravimetric applications where precision is required. The uniform pore distribution ensures consistent filtration performance across the entire sheet.
2. Can this filter paper be used with acidic or alkaline solutions?
The ashless cotton composition provides excellent chemical resistance to both acidic and alkaline solutions, though prolonged exposure to highly concentrated reagents may affect structural integrity. For optimal results, pre-wetting with a compatible solvent is recommended before filtration.
3. How does the black coloration benefit filtration processes?
The black dye enhances contrast against light-colored particles, improving visual detection of contaminants during qualitative analysis. This feature is particularly valuable in air monitoring and environmental sampling where particle identification is critical.
4. What storage conditions are recommended to maintain filter paper quality?
Store in a cool, dry environment (15-25°C) with relative humidity below 60%. Keep the original packaging sealed to prevent moisture absorption or particulate contamination, which could compromise filtration accuracy.
5. Are there alternative Whatman grades for similar applications?
For comparable applications, Whatman Grade 40 (ashless, 8µm retention) or Grade 42 (ashless, 2.5µm retention) may be considered, though these lack the black ribbon format. Grade 589/1 FF is specifically optimized for tasks requiring both high particle visibility and quantitative precision.
