Optimized for controlled laboratory processes, the Filter Circles, Qualitative, Grade 2, Dia.: 240 Mm, are designed for applications requiring a slightly slower filtration speed and increased absorbency compared to Grade 1. These filter circles, manufactured by Whatman, offer a filtration efficiency of 8 µm and have a thickness of 0.19 mm. With a weight of 103 g/m², they provide an extended filtration time of approximately 20 seconds. This extra absorbency makes them suitable for holding soil nutrients in plant growth trials and monitoring specific contaminants in the atmosphere and soil testing.
