Whatman® application specific filter, prepleated qualitative filter paper, Grade 2555 1/2, circles [Pack of 100]

Description

SPECIFICATIONS
Thickness 170 µm (typical)
Particle Retention 12 µm (in Liquid Max.)
Filtration Speed Approx. 55 s (Herzberg)
Flow Rate Medium fast
Basis Weight 75 g/m²

Savings in time required to quadrant-fold circles to fit conical filter funnels in repetitive or multiple analyses
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

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.
