Grade 1573 1/2 Qualitative Filter Paper Folded (Prepleated), 270mm, 100/Pk SKU: 10314752

Qualitative Filter Paper - 10314752

From student teaching labs to production QC departments, qualitative filter paper remains the workhorse for routine particle separation. Standard basis weight specifications provide predictable filter packing density for volumetric displacement calculations in funnel assemblies. In combination, controlled manufacturing delivers the documented retention, flow rate, and physical consistency that analytical and preparative filtration methods require.

Key Filter Paper Characteristics

• Standard construction provides the soft, conformable surface that seats properly in gravity filtration funnels without edge leakage.
• Pure cellulose fiber construction delivers consistent flow rates and predictable retention for general sample clarification and preparation.
• Wet strength sufficient for gentle handling during precipitate transfer while maintaining the rapid flow rates of qualitative grades.
• 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.

If your environmental monitoring program depends on sample comparability to determine trends, the production consistency of this filter paper protects your data validity. To address this, standard cellulose chemistry eliminates the need for specialized disposal procedures your general laboratory filtration generates. Make the decision for consistency and reliability, ensuring that your laboratory maintains its reputation for high-quality, error-free output.
