Grade 520 a 1/2 Qualitative Filter Paper Folded (Prepleated), 240mm, 100/Pk SKU: 10331451

Qualitative Filter Paper - 10331451

Pre-filtering turbid samples before instrumental analysis needs a paper grade that removes interfering particles while maintaining reasonable flow rates. Cellulose fiber matrix maintains structural integrity through standard gravity and light vacuum filtration conditions. For this reason, each sheet reflects production standards where fiber density, thickness, and retention characteristics are verified before lot release.

Key Filter Paper Characteristics

• Enhanced wet strength allows vacuum filtration at higher differential pressures without risking paper rupture mid-run.
• Standard qualitative cellulose filter paper provides reliable particle retention for gravity and vacuum filtration across routine laboratory workflows.
• Uniform fiber distribution across the sheet ensures consistent particle retention from edge to center for reproducible filtration results.
• Manufactured from high-purity cotton linters, qualitative filter paper provides a clean filtration surface with minimal fiber shedding.
• Medium porosity cellulose matrix captures suspended solids while maintaining the throughput needed for efficient batch processing.

Whether your method requires simple clarification or precise gravimetric determination, the documented specifications above define what this paper delivers. In practice, cotton linter cellulose provides the clean fiber background your general analytical methods need without the cost of specialty grades. Elevate the quality of your analytical data today by standardizing on a filtration product built to meet the exact specifications of your applications.
