Filtry jakościowe Grade 2555 1/2

Średnio szybki papier filtracyjny stosowany do filtracji zacieru przy oznaczaniu ekstraktu w słodzie i brzeczce oraz do usuwania dwutlenku węgla z piwa.
A medium fast filter paper 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.

Time-saving Whatman qualitative grades are offered in this convenient form, which gives major advantages over flat circles.
