Beschreibung

Allgemeine Beschreibung

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 0860 ½ : 7-12 μm (medium fast, smooth filter paper)
Comparable to grade 0858 but with a smooth surface, slightly thinner and faster.
