Product Overview
Whatman Grade 2 filter paper is a high-performance, acid-free qualitative paper designed for medium-speed filtration in laboratory settings. With an 8-micron particle retention rating, it ensures efficient separation of fine precipitates while maintaining excellent flow rates. The paper is manufactured from pure cotton linters, ensuring minimal ash content and consistent filtration results. Its ignition-strength properties make it suitable for applications requiring thermal stability, such as gravimetric analysis. The uniform thickness and smooth surface minimize clogging, ensuring reliable performance across multiple filtrations. Each sheet is individually inspected to meet IPCertified standards, guaranteeing batch-to-batch consistency. The 15.0CM diameter provides ample surface area for standard lab funnels, while the pack of 100 sheets offers cost-effective bulk usage. Its chemical compatibility with most organic and inorganic solvents further enhances its versatility in diverse laboratory workflows.
FAQs
1. What is the particle retention capacity of Whatman Grade 2 filter paper?
This filter paper has an 8-micron particle retention capacity, making it ideal for medium-speed filtration tasks where fine precipitate separation is required.
2. Can this filter paper be used for gravimetric analysis?
Yes, Whatman Grade 2 is specifically designed for gravimetric analysis due to its low ash content and consistent weight properties after ignition.
3. Is this filter paper compatible with organic solvents?
The paper is chemically stable with most organic and inorganic solvents, though we recommend checking specific solvent compatibility for your application.
