Qualitative Filter Paper - 1114-150
Gravity filtration methods for removing suspended solids require filter paper that seats cleanly in funnels and retains particles consistently. Controlled fiber density produces documented flow rate and retention characteristics that remain consistent across production lots. For this reason, standardized manufacturing protocols produce papers with retention and flow characteristics that remain constant from the first batch to the last.
Key Filter Paper Characteristics
- Non-hardened cellulose delivers the flow rates and retention that routine methods require at practical cost per determination.
- Standard qualitative cellulose filter paper provides reliable particle retention for gravity and vacuum filtration across routine laboratory workflows.
- Standard basis weight and thickness specifications provide predictable packing density for volumetric calculations in gravity funnels.
- Uniform fiber distribution across the sheet ensures consistent particle retention from edge to center for reproducible filtration results.
- Available in precut circles and sheet stock to match funnel sizes and custom cutting requirements across laboratory applications.
Whether your method requires simple clarification or precise gravimetric determination, the documented specifications above define what this paper delivers. 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.
