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.

Features and Benefits

• 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.
