Details
This Whatman,10311887, Grade 597 filter paper has a diameter of 58 mm and comes in a pack of 500.
Fast filter paper. Stated in a number of standards and methods [e.g., Aflatoxin determination in animal feed (BS 5766-7) and Mercury determination in sludge (EPA method 105)].
Features:
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.
