Grade 597 Qualitative Filter Paper Standard Grade, Circle, 55mm, 100/Pk SKU: 10311807

Qualitative Filter Paper - 10311807

Gravity filtration methods for removing suspended solids require filter paper that seats cleanly in funnels and retains particles consistently. Controlled fiber density produces documented flow rate and retention characteristics that remain consistent across production lots. Altogether, certificate of conformance documentation accompanies each lot, providing traceability for quality systems and regulatory audit requirements.

Key Filter Paper Characteristics

• Compatible with standard glass and plastic filter funnels, qualitative paper integrates into existing gravity filtration setups without modification.
• Manufactured from high-purity cotton linters, qualitative filter paper provides a clean filtration surface with minimal fiber shedding.
• Pure cellulose without strengthening additives ensures the lowest possible extractable background for sensitive analytical methods.
• Smooth surface finish supports clear visual inspection of retained material and clean separation from the collected filtrate.
• Medium porosity cellulose matrix captures suspended solids while maintaining the throughput needed for efficient batch processing.

Maintaining accreditation requires documented traceability at every step, and the grade specifications above support your audit readiness. Cotton linter cellulose provides the clean fiber background your general analytical methods need without the cost of specialty grades. Take control of your sample preparation variables and ensure that your data reflects the true nature of your work, rather than the quality of your consumables.
