Qualitative Filter Paper, 185 mm dia, Cellulose, Grade 602 h 1/2

A dense prepleated filter paper for collecting very small particles and removing fine precipitates. Time-saving Whatman™ qualitative grades are offered in this convenient form, which gives major advantages over flat circles.

Savings in time required to quadrant-fold circles to fit conical filter funnels in repetitive or multiple analysesDecreased overall filtration time because of the extra surface area exposed; the normal slow down of filtration speed due to the loading of particulate is postponedIncreased total loading capacity as more filter area is availableMaintains flow rate due to the reduction in filter paper contact with funnel side and the self-supporting shape of the filter itselfThe prepleating does not significantly affect any of the technical data and the same figures may be used for the flat circlesUsed in sample preparation, e.g., in the beverage industry for residual sugar determination, acidic spectra, refractometric analysis, and HPLC
