Pleated to save time and achieve optimal fit in conical filter funnels. Whatman™ Qualitative Filter Paper: Grade 597½ Pleated Circles provide extra surface area to increase total loading capacity.

Folded filter is used for many routine analytical applications in various industries. Pleated paper enhances and eases filtering process.

Saves time in repetitive or multiple analyses
Decreases overall filtration time; normal slow down due to particulate loading is eliminated
Increases total loading capacity
Maintains flow rate; contact with funnel is reduced, shape of filter is self-supporting
Pleating does not significantly affect technical data; same figures may be used with flat circles
Grade 597½ is a medium fast paper with medium to fine particle retention
Applications include:
- Food testing; determination of fat content
- Removal of carbon dioxide and turbidity from beverages
