Grade 202 Cellulose Filter Paper, 15cm Circle, 100/Pk SKU: 5202-150

Qualitative Filter Paper - 5202-150

Separating precipitates from analytical solutions requires a cellulose matrix with the right balance of retention and flow rate. Standard basis weight specifications provide predictable filter packing density for volumetric displacement calculations in funnel assemblies. From fiber selection through final inspection, the manufacturing process ensures every sheet meets the performance specifications of its grade.

Key Filter Paper Characteristics

• Basis weight of 82g/m² indicates the fiber mass per unit area that controls retention, flow rate, and wet strength.
• 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.
• Pure cellulose fiber construction delivers consistent flow rates and predictable retention for general sample clarification and preparation.
• Wet-strengthened construction maintains paper integrity during prolonged vacuum and pressure filtration of aqueous samples.

If your environmental monitoring program depends on sample comparability to determine trends, the production consistency of this filter paper protects your data validity. In these cases, sheet-to-sheet consistency means your training investment carries forward as new staff learn the same predictable filtration behavior. 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.
