Whatman 10347008 Filter Circles, 70mm Dia, 8 Ruled, 100/pk

These filter circles are designed for routine investigation of foreign particles and general laboratory filtration. They are commonly used in food and beverage testing, particulate analysis, and contamination inspection, where visual identification after filtration is important.

The Grade 8 ruled format features printed green grid lines on white cellulose paper, which allow users to visually examine, count, and analyze retained particles more easily. This makes it ideal for quality control and contamination checks.

These filters are made from high-purity cellulose fibers, providing consistent porosity and reliable filtration performance. The cellulose construction supports routine qualitative filtration and visual particle inspection applications.

The 70 mm diameter is compatible with many standard laboratory funnels and holders, making it suitable for small-to-medium sample volumes. This size helps improve efficiency while minimizing sample waste.

Grade 8 ruled filter papers provide medium particle retention with good flow rate, allowing effective removal of suspended solids while maintaining visibility of captured material for inspection and counting.
