General description
- 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 0858 ½: 7-12 μm (medium fast, grained filter paper)
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.
