Whatman 10311862 Filter Circles, 12.7mm Dia, Grade 597, 1000/pk (PN:10311862)

Whatman Grade 597 filter paper is designed for routine laboratory filtration tasks, including food testing, environmental analysis, and general sample preparation. It is commonly used to remove turbidity, particulates, or residues in applications like beverage testing and chemical analysis.

This filter paper offers medium-to-fine particle retention in the 4–7 µm range, making it suitable for filtering fine precipitates while maintaining a relatively fast flow rate.

Grade 597 is considered a medium-fast filter paper, with a typical filtration speed of about 70 seconds per 100 mL. This balance of speed and retention makes it ideal for everyday lab workflows.

These filter circles are made from high-quality cellulose fibers, providing consistent performance, good wet strength, and compatibility with a wide range of aqueous solutions.

This product features a 12.7 mm diameter, Grade 597 qualitative filter paper, and comes in a pack of 1000 circles. It is non-sterile, hydrophilic, and designed for use in standard laboratory filtration setups.
