Ashless Quantitative Filter Paper 125mm

This professional Ashless Quantitative Filter Paper is a high-purity laboratory filtration media engineered for quantitative analysis and gravimetric testing workflows. Manufactured as a Grade 41 equivalent with a 125mm diameter, this ashless circular filter paper features a fast filtration speed and a loose structure designed specifically to retain coarse particles and gelatinous precipitates efficiently.

Highly relied upon across analytical chemistry laboratories, environmental monitoring stations, and industrial quality control systems, these Whatman 41 type filters leave a negligible ash residue when ignited. They are an ideal choice for filtering large particle precipitates, assessing air pollution levels, and analyzing soil or food samples where accurate gravimetric measurements are essential for strict quality standards.
