Grade 202 Cellulose Filter Paper, 9 cm Circle, 100/Pk SKU: 5202-090

Qualitative Filter Paper - 5202-090

Sample clarification before instrumental analysis starts with a filter paper that captures interfering particles without introducing extractable contamination. Standard basis weight specifications provide predictable filter packing density for volumetric displacement calculations in funnel assemblies. In combination, certificate of conformance documentation accompanies each lot, providing traceability for quality systems and regulatory audit requirements.

Key Filter Paper Characteristics

• Medium porosity cellulose matrix captures suspended solids while maintaining the throughput needed for efficient batch processing.
• Wet-strengthened construction provides the mechanical durability needed for technical filtration applications under sustained vacuum.
• 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.
• Smooth surface finish supports clear visual inspection of retained material and clean separation from the collected filtrate.

Whether your method requires simple clarification or precise gravimetric determination, the documented specifications above define what this paper delivers. In these cases, consistent sheet-to-sheet performance reduces the variability your operators encounter during high-volume daily filtration workflows. 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.
