Product Overview
Whatman Grade 1574 FF is a high-performance cellulose filter paper engineered for fast, efficient filtration in laboratory settings. With an 8-micron particle retention rating, this grade is optimized for applications requiring rapid flow without compromising filtration quality. The pure cellulose composition ensures minimal extractables, making it compatible with a wide range of aqueous and organic solvents. Its smooth surface and uniform pore structure reduce clogging, while the fast flow rate significantly cuts down processing time. The paper’s inherent wet strength and chemical resistance allow for reliable performance even under demanding conditions. Each sheet undergoes rigorous quality control to guarantee consistency in thickness, weight, and filtration efficiency. The 125mm diameter is ideal for standard funnels, and the pack of 100 ensures ample supply for repetitive experiments. Unlike slower grades, 1574 FF balances speed and retention, eliminating the need for pre-filtration in many cases. Its neutral pH and low ash content further enhance its suitability for sensitive applications where contamination must be minimized.
FAQs
1. What is the particle retention capacity of Whatman Grade 1574 FF?
This grade retains particles down to 8 microns, making it suitable for moderate-clarity filtration where speed is prioritized over ultra-fine retention.
2. Can this filter paper be used with acidic or alkaline solutions?
The cellulose composition provides good chemical resistance to mild acids and bases, but prolonged exposure to strong reagents may degrade the paper over time.
3. How does the flow rate compare to standard Whatman Grade 1?
Grade 1574 FF offers a significantly faster flow rate than Grade 1 due to its larger pore size, though it sacrifices some fine-particle retention in exchange for speed.
4. Is this filter paper pre-sterilized or autoclavable?
The paper is not pre-sterilized but can be autoclaved at 121°C for 15 minutes without compromising its structural integrity or filtration performance.
5. What alternatives exist for finer particle retention with similar flow rates?
For applications requiring 5-micron retention with comparable speed, Whatman Grade 413 or Grade 415 could be considered, though their flow rates will be slightly slower than 1574 FF.
