General description
Time-saving Whatman qualitative grades are offered in this convenient form, which gives major advantages over flat circles:
Grade 2555 ½ : 7-12 mm (medium fast filter paper)
A medium fast filter paper. Application specific, used for the filtration of the mash for the determination of the extract in malt and wort and for removing carbon dioxide from beer.
- 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
