Grade 597 1/2 Qualitative Filter Paper Folded (Prepleated), 240mm, 100/Pk SKU: 10311851

Qualitative Filter Paper - 10311851

Gravity filtration setups require paper that wets uniformly, seats flat in funnels, and retains particles at the rated threshold. Smooth surface finish allows clear visual assessment of retained solids and supports clean separation of precipitates from filtrate. In practice, documented grade specifications provide laboratories with the technical data needed to select appropriate papers without preliminary testing.

Key Filter Paper Characteristics

• 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.
• Uniform fiber distribution across the sheet ensures consistent particle retention from edge to center for reproducible filtration results.
• Wet strength sufficient for gentle handling during precipitate transfer while maintaining the rapid flow rates of qualitative grades.
• Compatible with standard glass and plastic filter funnels, qualitative paper integrates into existing gravity filtration setups without modification.

When your application makes the filter paper part of the measurement, the ash and weight specifications above define its analytical contribution. Under these conditions, wide retention range availability across the qualitative grade family lets you optimize each application in your sample preparation workflow. 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.
