Grade 597 Seed Testing Paper, Circle, 90mm, 100/Pk SKU: 10311809

Qualitative Filter Paper - 10311809

Gravity filtration setups require paper that wets uniformly, seats flat in funnels, and retains particles at the rated threshold. Available in circles, sheets, and prefolded formats to match specific funnel geometries and sample processing workflows. By design, rigorous quality control at every production stage ensures physical properties align with published grade specifications before distribution.

Key Filter Paper Characteristics

• At 85g/m² nominal basis weight, the paper provides the mass uniformity needed for reproducible gravimetric determinations.
• Pure cellulose fiber construction delivers consistent flow rates and predictable retention for general sample clarification and preparation.
• Medium porosity cellulose matrix captures suspended solids while maintaining the throughput needed for efficient batch processing.
• 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.

If your laboratory runs standardized filtration protocols, the lot-level consistency of this filter paper protects your method reproducibility. Cotton linter cellulose provides the clean fiber background your general analytical methods need without the cost of specialty grades. Secure your research outcomes by partnering with a filtration solution that understands your need for speed, accuracy, and reproducibility.
