A staple reagent in organic synthesis and formulation chemistry, the Quantitative Filter Circles, Grade 40, Ø 70 Mm serve as an essential tool for precise filtration processes. These filter circles, manufactured by Whatman, are particularly suitable for gravimetric analysis of various components in cement, clay, iron, and steel products. They also function as a primary filter for separating solid matter from aqueous extracts in general soil analysis. Furthermore, these filter circles are ideal for quantitative determination of sediments in milk and as a pure analytical grade clean-up filter for solutions prior to Atomic Absorption Spectroscopy (AAS) analysis. With a Type Sorte 40 designation, these filters offer a moderate filtration speed and retention capacity, ensuring accurate results in a wide range of applications.
