Filter Paper, round, folded, Grade 597 ½, 150 mm, 100 pc/PAK

Properties:

• Medium-fast filtering
• Filtration speed of 70 s/100 ml

A filter paper for medium-fast filtration, for the retention of medium to small sized particles. It is used in many 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).

• 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.

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. Also available in flat stock form as Grade 597.
Grade 597 ½: 4-7 µm
