Qualitative Filter Paper - 10347525
Sample clarification before instrumental analysis starts with a filter paper that captures interfering particles without introducing extractable contamination. Available in circles, sheets, and prefolded formats to match specific funnel geometries and sample processing workflows. Together, rigorous quality control at every production stage ensures physical properties align with published grade specifications before distribution.
Key Filter Paper Characteristics
- Available in precut circles and sheet stock to match funnel sizes and custom cutting requirements across laboratory applications.
- 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.
- Manufactured to a basis weight of 44g/m², each sheet delivers the documented mass consistency that gravimetric methods require.
- Pure cellulose fiber construction delivers consistent flow rates and predictable retention for general sample clarification and preparation.
Reporting filtration parameters alongside your analytical results demands documented grade, retention, and lot traceability for reviewer confidence. 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.
