| Features and Benefits: | • Very Fast flow rate • Retention of coarse and gelatinous precipitates • Nominal particle retention rating of 20–25 µm • Fast filtration speed (Herzberg 37 s) • Fluted (pre-pleated) for compatibility with conical filter funnels without the need for further folding |
| General description: | A prepleated filter paper widely used for general purpose filtration. Has excellent particle retention and a good filtration speed and loading capacity. • Savings in time required to quadrant-fold circles to fit conical filter funnels in repetitive or multiple analyses. • Decreased overall filtration time because of the extra surface area exposed; the normal slow down of filtration speed due to the loading of particulate is postponed. • Increased total loading capacity as more filter area is available. • Maintained flow rate due to the reduction in filter paper contact with funnel side and the self-supporting shape of the filter itself. • The prepleating does not significantly affect any of the technical data, and the same figures may be used for the flat circles. • Time-saving Whatman qualitative grades are offered in this convenient form, which gives major advantages over flat circles. Grade 4V: 25 um Also available in flat stock form as Grade 4. |
