Whatman Qualitative Filter Paper Grade 0858 ½ Folded (Prepleated) 185 mm

Description

Grained, with medium fast flow rate and medium retention. A universal filter paper, used for the filtration of extracts, oils, beer, syrups etc.; also applied in filter presses or for the aspiration of liquids.

• 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.
