Product Overview
Whatman Grade GF/F glass microfibre filters are engineered for superior particulate retention, offering a 0.7?m nominal pore size that ensures high efficiency in trapping fine particles. These binder-free filters are composed of 100% borosilicate glass microfibres, providing excellent chemical resistance and thermal stability up to 500?C. The uniform structure allows for consistent flow rates and high loading capacity, making them ideal for demanding filtration tasks. Their low extractable content minimizes interference in analytical procedures, while the smooth surface facilitates easy particle recovery. Available in a wide range of diameters, sheets, and reels, these filters adapt to diverse laboratory setups, from small-scale experiments to large-volume processing. The GF/F grade is particularly valued for its balance between retention efficiency and flow rate, ensuring reliable performance in critical applications. Whether used for air pollution monitoring, liquid clarification, or sample preparation, these filters deliver precision and reproducibility. Their compatibility with most solvents and reagents further enhances their versatility in laboratory environments.
FAQs
1. What is the retention efficiency of Whatman GF/F filters?
Whatman GF/F filters offer a 0.7?m nominal particle retention, making them highly effective for fine particulate filtration.
2. Are these filters compatible with organic solvents?
Yes, these filters are chemically resistant and compatible with most organic solvents and aqueous solutions.
3. Can GF/F filters be used for air monitoring?
Yes, their high retention efficiency makes them suitable for air pollution monitoring and particulate sampling.
