Grade 597 1/2 Qualitative Filter Paper Folded (Prepleated), 320mm, 100/Pk SKU: 10311853

Qualitative Filter Paper - 10311853

Laboratories processing dozens of samples daily need a qualitative filter paper that performs reliably from the first sheet to the last. Natural cellulose wettability eliminates the pre-wetting step required by hydrophobic membranes in aqueous sample filtration. Certificate of conformance documentation accompanies each lot, providing traceability for quality systems and regulatory audit requirements.

Key Filter Paper Characteristics

• Untreated cellulose construction provides the pure, unmodified surface appropriate for routine filtration and general sample preparation.
• Pure cellulose fiber construction delivers consistent flow rates and predictable retention for general sample clarification and preparation.
• Standard qualitative cellulose filter paper provides reliable particle retention for gravity and vacuum filtration across routine laboratory workflows.
• Smooth surface finish supports clear visual inspection of retained material and clean separation from the collected filtrate.
• At 85g/m² nominal basis weight, the paper provides the mass uniformity needed for reproducible gravimetric determinations.

Scaling your method from development to routine production requires paper consistency at every lot, and the specifications above provide that assurance. For exactly this reason, rapid wetting and uniform pore distribution reduce the setup time your operators spend preparing each filtration run. Make the decision for consistency and reliability, ensuring that your laboratory maintains its reputation for high-quality, error-free output.
