Ahlstrom 6310-5000 Qualitative Filter Paper, Grade 631, 500 mm, 100/pk

Grade 631 filter paper is commonly used for filtration of coarse particles and gelatinous precipitates, such as metal hydroxides and biological suspensions. It is widely applied in environmental testing, air monitoring, and general laboratory sample preparation.

This filter paper provides approximately 10 µm particle retention with medium filtration speed, allowing efficient separation of larger particles while maintaining good flow rates for routine lab work.

Yes, Grade 631 is designed for applications requiring higher flow rates, making it ideal for processing samples with heavier particulate loads or when fast filtration is needed without excessive clogging.

This filter paper is suitable for organic solutions, biological fluids, and environmental samples, especially those containing coarse or suspended particles that require efficient clarification.

A 500 mm filter provides a large surface area for high-volume filtration, improving throughput and reducing the need for frequent filter changes in industrial or large-scale laboratory processes.
