Grade GF/A

These filters offer fine particle retention and high flow rate, as well as good loading capacity, making them ideal for a variety of liquid and air filtration applications. Grade GF/A binder-free Whatman glass microfiber filters are available in a wide range of sizes, including circles and sheets.
With a nominal particle retention of 1.6µm at 98% efficiency, they are well-suited for handling large sample volumes in a range of applications.

Applications:

• Water and air pollution monitoring and wastewater filtration
• Foodstuff analysis
• Filtering algae and bacteria cultures
• Protein filtration
• Radioimmunoassay for weak β emitters
• Gravimetric determination of airborne particulates, stack sampling, and absorption methods of air pollution monitoring
