Grade 1573 1/2 Qualitative Filter Paper Folded (Prepleated), 240mm, 100/Pk SKU: 10314751

Qualitative Filter Paper - 10314751

From student teaching labs to production QC departments, qualitative filter paper remains the workhorse for routine particle separation. Manufactured without chemical hardening or acid washing, qualitative cellulose delivers the unmodified surface properties routine filtration requires. With this in mind, certificate of conformance documentation accompanies each lot, providing traceability for quality systems and regulatory audit requirements.

Key Filter Paper Characteristics

• Standard basis weight and thickness specifications provide predictable packing density for volumetric calculations in gravity funnels.
• Resin treatment provides the tensile strength to resist tearing under vacuum, even when processing large sample volumes.
• Smooth surface finish supports clear visual inspection of retained material and clean separation from the collected filtrate.
• Standard qualitative cellulose filter paper provides reliable particle retention for gravity and vacuum filtration across routine laboratory workflows.
• Pure cellulose fiber construction delivers consistent flow rates and predictable retention for general sample clarification and preparation.

If your workflow includes both routine clarification and specialized quantitative methods, stocking this versatile grade reduces your inventory complexity. Consistent sheet-to-sheet performance reduces the variability your operators encounter during high-volume daily filtration workflows. 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.
