Grade 1573 Qualitative Filter Paper Wet-Strengthened, Circle, 185mm, 100/Pk SKU: 10314714

Qualitative Filter Paper - 10314714

Sample clarification before instrumental analysis starts with a filter paper that captures interfering particles without introducing extractable contamination. Controlled fiber density produces documented flow rate and retention characteristics that remain consistent across production lots. As designed, lot-level verification of retention, thickness, and ash content ensures predictable performance when scaling from method development to routine analysis.

Key Filter Paper Characteristics

• 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.
• Wet strength sufficient for gentle handling during precipitate transfer while maintaining the rapid flow rates of qualitative grades.
• Pure cellulose fiber construction delivers consistent flow rates and predictable retention for general sample clarification and preparation.
• Wet-strengthened fiber matrix withstands extended contact with aqueous solutions without the disintegration that limits untreated papers.

When your budget requires balancing performance with cost efficiency, the documented consistency above ensures you're not paying for premium features you don't need. To address this, cotton linter cellulose provides the clean fiber background your general analytical methods need without the cost of specialty grades. 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.
