LabEXACT 12K903 qualitative filter paper

This pack contains 100 cellulose discs with a uniform 8 µm pore size. The medium-slow flow rate suits gravimetric analysis and general laboratory clarification. Each disc measures 11 cm in diameter and 0.17 mm thick. The grade 2 material meets FDA standards for use with gases and liquids.

Check chemical compatibility and filtration speed

Verify that cellulose is resistant to the solvents or reagents in your workflow. Confirm that the medium-slow porosity matches the required throughput for your sample volumes. Ensure the 11 cm diameter fits your existing funnel or holder. The flat disc shape requires no fluted adapter.

Replaces slower or inconsistent filter grades

Upgrade from papers with variable pore distribution when repeatable retention is critical. The jump is worth it for labs needing FDA-listed media for regulatory work. It does not suit applications requiring fluted geometry or higher wet-strength membranes. Buyers needing larger diameters or smaller pore sizes should look elsewhere.

Questions about this item

Does the LABEXACT 12K903 filter paper pack include any funnels or holders, or are they sold separately?

The pack contains 100 qualitative filter paper discs of 11.0 cm diameter. Funnels or holders are not included and must be purchased separately.

Which pore size should I choose between the 8 µm grade and other grades for fine particle retention?

This specific model has a fixed pore size of 8 µm. Other grades with different pore sizes are separate products not covered by this listing.

What does the 8 µm pore size mean when filtering a typical laboratory liquid sample?

The 8 µm pores retain particles of that size and larger while allowing liquids to pass at a medium-slow flow rate suitable for qualitative analysis.
