Product Overview
Whatman Grade 1V cellulose filter paper is a versatile, high-purity filtration medium designed for general laboratory applications requiring consistent performance. Engineered with a medium flow rate and 11?m particle retention, this filter paper balances efficiency and clarity, making it ideal for routine filtration tasks. The cellulose composition ensures chemical compatibility with a wide range of solvents and aqueous solutions, while the uniform pore structure minimizes clogging for smoother operation. Each sheet undergoes stringent quality control to maintain thickness consistency and mechanical strength, reducing the risk of tearing during use. The neutral pH and low ash content (<0.06%) further enhance its suitability for sensitive applications where contamination must be minimized. Available in multiple diameters, this filter paper adapts to various funnel sizes and filtration setups, providing flexibility without compromising performance. Its smooth surface texture facilitates even particle distribution, improving filtration uniformity across the entire sheet. Whether used for clarifying liquids, removing precipitates, or preparing samples, Whatman Grade 1V delivers reliable results with minimal extractables, ensuring data integrity in analytical workflows.
FAQs
1. What is the particle retention capacity of Whatman Grade 1V filter paper?
The particle retention capacity is 11?m, making it suitable for filtering fine particulates while maintaining a medium flow rate.
2. Can this filter paper be used with organic solvents?
Yes, the cellulose composition is compatible with most organic solvents and aqueous solutions, though compatibility should be verified for specific chemicals.
3. How does the flow rate compare to other Whatman grades?
Grade 1V offers a medium flow rate, faster than Grade 42 but slower than Grade 1, balancing speed and retention efficiency.
4. What is the ash content of this filter paper?
The ash content is less than 0.06%, ensuring minimal residue that could interfere with sensitive analyses.
5. Is this filter paper pre-sterilized?
No, Whatman Grade 1V is not pre-sterilized and should be sterilized separately if required for aseptic applications.
