Whatman® glass microfiber filters, Grade GF/A, circles

Whatman® Grade GF/A glass microfiber filters are binder-free filters designed for high capacity filtration. These filters are ideal for applications requiring fast flow rates and fine particle retention. With a nominal particle retention of 1.6 μm at 98% efficiency, these filters are specifically suited for large-volume liquid and air filtration.

Key Features & Benefits:

1. High Efficiency:
   • Nominal Particle Retention: 1.6 μm at 98% efficiency, ensuring fine filtration for a wide range of applications.
   • Binder-Free: No binders are used in the production of these filters, ensuring minimal interference with samples and optimal filtration performance.
2. Fast Flow Rates:
   • The fast flow rates make these filters suitable for large-volume filtration, allowing for rapid filtration of liquid and air samples without compromising efficiency.
3. High Capacity:
   • Designed to handle high sample volumes, Grade GF/A filters are ideal for applications such as water, air pollution monitoring, and wastewater filtration, where large volumes of liquid or air need to be processed quickly and effectively.

Applications:

• Water and Air Pollution Monitoring: Efficient for filtering out particulates from water and air samples in environmental analysis.
• Wastewater Filtering: Effective in filtering large volumes of wastewater for analysis.
• Foodstuff Analysis: Suitable for filtration in food safety and quality control testing.
• Algae and Bacteria Cultures: Used in microbiology for the filtration of microbial cultures.
• Protein Filtration: Ideal for separating proteins in various biochemical processes.
• Radioimmunoassay of Weak β Emitters: Used in sensitive assays involving radioactive materials.
• Gravimetric Determination of Airborne Particulates: Helpful in determining the mass of airborne particles in environmental monitoring studies.

Additional Notes:

• Field of Use: These filters are intended for internal research use only and are not suitable for diagnostic use or resale.
