Produced to ensure dependable processing results, these Qualitative Filter Circles, Grade 2, with a diameter of 47 mm, offer enhanced retention and absorption capabilities compared to their grade 1 counterparts. This is achieved through a slight increase in filtration time and greater absorbency, making them suitable for applications such as holding soil nutrients in plant growth trials and monitoring specific contaminants in the atmosphere and soil testing. Manufactured by Whatman, these filter circles boast a weight of 103 g/m² and a thickness of 0.19 mm, ensuring efficient filtration within the 8 µm particle size range.
