Designed for professional use, these Quantitative Filter Papers, specifically the Fillter Circles, Grade 541, with a diameter of 125 mm, are ideal for fast filtration of coarse particles and gelatinous precipitates in acid/alkali solutions during gravimetric analysis. Manufactured by Whatman, these filter circles boast a basis weight of 82 g/m², a typical thickness of 155 µm, and a filtration time of just 3 seconds, ensuring efficient separation processes. With a particle retention in liquid ranging from 20 to 25 µm, these filters effectively capture impurities while allowing for rapid filtration speeds, as demonstrated by their Herzberg filtration speed of 34 s. The ash content is less than 0.006 %, making them suitable for various applications within the lab environment.
