Grade 8 Qualitative Filter Paper, Ruled, 70mm Circle, 100/Pk SKU: 10347008

Qualitative Filter Paper - 10347008

Separating precipitates from analytical solutions requires a cellulose matrix with the right balance of retention and flow rate. Available in circles, sheets, and prefolded formats to match specific funnel geometries and sample processing workflows. As designed, documented grade specifications provide laboratories with the technical data needed to select appropriate papers without preliminary testing.

Key Filter Paper Characteristics

• Smooth surface finish supports clear visual inspection of retained material and clean separation from the collected filtrate.
• Wet strength sufficient for gentle handling during precipitate transfer while maintaining the rapid flow rates of qualitative grades.
• Untreated cellulose construction provides the pure, unmodified surface appropriate for routine filtration and general sample preparation.
• Available in precut circles and sheet stock to match funnel sizes and custom cutting requirements across laboratory applications.
• Standard qualitative cellulose filter paper provides reliable particle retention for gravity and vacuum filtration across routine laboratory workflows.

If you're transitioning from qualitative screening to quantitative gravimetric work, the documented ash content above confirms this paper's suitability. For this application, sheet-to-sheet consistency means your training investment carries forward as new staff learn the same predictable filtration behavior. Make the decision for consistency and reliability, ensuring that your laboratory maintains its reputation for high-quality, error-free output.
