| Features and Benefits: | • Nominal particle retention rating of 25 µm • Fast filtration (Herzberg 38 s) • Chemically stable resin provides increased wet-strength • Fluted (pre-pleated) filter sheet for ease-of-use and compatibility with conical funnels • Smooth filter surface for efficient recovery of precipitates |
| General description: | Time-saving Whatman qualitative grades are offered in folded (prepleated) form, which gives major advantages over flat circles: • 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 Grade 114V: 25 μm (fast, smooth filter paper) Strong filter with very fast flow rate. Ideal for coarse particles and gelantanious precipitates. Smooth surface. |
