Whatman 10314745 Qualitative Filter Paper 12-25 µm, 150 mm (100/Pack)

This Whatman,10314745, Grade 1573 ½ filter paper has a diameter of 150 mm and comes in a pack of 100.

Grade 1573 ½: 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).

A medium fast filter paper with high wet strength. This paper has the same chemical resistance characteristics as Grade 1573

Features:
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.
