Brand: Whatman

Properties: Fast filtration Filtration speed of 25 s/100 ml A paper with a high filtration speed and high wet strength. With a very smooth surface for easier scraping or washing off of the precipitate. Resistant to sulphuric and nitric acid solutions (up to 40% at 50 °C), hydrochloric acid solutions (up to 10% at 100 °C, 20% at 60 °C, 25% at 20 °C) and alkaline solutions (up to 10% at 20 °C). 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 theNäytä lisää
