Filtry jakościowe Grade 1574 1/2

Średnio szybki papier filtracyjny o wysokiej wytrzymałości w stanie mokrym. Papier ten ma takie same właściwości w zakresie odporności chemicznej jak papier klasy 1573.
A medium fast filter paper with high wet strength. This paper has the same chemical resistance characteristics as Grade 1573.

• 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.

Also available in flat stock form as Grade 1574.
