Whatman 10312753 Grade 604 1/2 Qualitative Filter Papers for coarse precipitates FF 320 mm 100/Pk, 100 per pack

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

A medium fast Filter paper with medium to fine particle retention. Used for a wide variety of analytical routine applications in different industries like food testing (e.g., determination of fat content) or removal of carbon dioxide and turbidity from beverages (e.g., beer analysis). Also available in flat stock form as Grade 597.

Features:

• Savings in time required to quadrant-fold circles to fit conical Filter funnels in repetitive or multiple analysis.
• 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.
