Qualitative Filter Paper - 5226-200

Gravity filtration methods for removing suspended solids require filter paper that seats cleanly in funnels and retains particles consistently. Medium retention grades capture suspended solids while maintaining flow rates suitable for routine laboratory sample throughput requirements. In combination, quality-controlled production produces filter paper with the documented consistency that reproducible analytical and preparative methods demand.

Key Filter Paper Characteristics

• 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.
• Standard qualitative cellulose filter paper provides reliable particle retention for gravity and vacuum filtration across routine laboratory workflows.
• At 87g/m² nominal basis weight, the paper provides the mass uniformity needed for reproducible gravimetric determinations.
• Wet strength sufficient for gentle handling during precipitate transfer while maintaining the rapid flow rates of qualitative grades.

When your application makes the filter paper part of the measurement, the ash and weight specifications above define its analytical contribution. To meet this need, cotton linter cellulose provides the clean fiber background your general analytical methods need without the cost of specialty grades. Make the decision for consistency and reliability, ensuring that your laboratory maintains its reputation for high-quality, error-free output.
