| Features and Benefits: | • 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. |
| General description: | Time-saving Whatman qualitative grades are offered in this convenient 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 1573 ½ : 12-25 mm (fast, smooth filter paper) A fast filter paper with high wet strength. It has a very smooth surface making it easy to scrape or wash off precipitate. Resistant against: sulfuric and nitric acid solutions (up to 40% at 50°C), hydrochloric (up to 10% at 100°C, 20% at 60°C, 25% at 20°C), alkalis (up to 10% at 20°C). |
