Whatman Quantitative Filter Paper, Ashless, Grade 41 Circles, Diam. 90 Mm, Pack Of 100 Whatman Paper

This Whatman 24.0cm, grade 2V, folded filter paper is widely used for general purpose filtration. It is slightly more retentive than Whatman grade 1. It has excellent particle retention along with a good filtration speed and loading capacity. This grade has a major advantage over flat circles because there is no time spent quadrant-folding circles to fit conical filter funnels in repetitive or multiple analysis. It provides a maintained flow rate because of reduction in filter paper contact with funnel side and the self-supporting shape of the filter. Prepleating does not significantly affect any technical data. Retention: 8µm. Diameter: 24.0cm. 100/Pack. Whatman #: 1202-240. 24.0cm Grade 2V; folded Major advantage over flat circles; no time spent quadrant-folding circles to fit conical filter funnels in repetitive or multiple analysis Extra surface area results in decreased overall filtration time; increased total loading capacity because more filter area is available
