GE Whatman* Grade 597 ¹/₂ Qualitative Filter Papers

• The prepleating does not significantly affect any of the technical data, and the same figures may be used for the flat circles.
• Savings in time required to quadrant-fold circles to fit conical filter funnels in repetitive or multiple analyses.
• Maintained flow rate due to the reduction in filter paper contact with funnel side and the self-supporting shape of the filter itself.
• Increased total loading capacity as more filter area is available.
• 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.

Grade 597 ¹/₂: 4-7 µm

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).
