Qualitative Filter Paper - 5230-110
Laboratories processing dozens of samples daily need a qualitative filter paper that performs reliably from the first sheet to the last. Uniform pore distribution across the sheet area ensures consistent particle capture from center to edge during gravity filtration. As designed, each sheet reflects production standards where fiber density, thickness, and retention characteristics are verified before lot release.
Key Filter Paper Characteristics
- Uniform fiber distribution across the sheet ensures consistent particle retention from edge to center for reproducible filtration results.
- Resin-bonded fiber structure resists progressive weakening that causes standard papers to fail during extended vacuum filtration cycles.
- Standard construction provides the soft, conformable surface that seats properly in gravity filtration funnels without edge leakage.
- At 25-30um rated retention, the fiber matrix captures particles above the threshold while allowing smaller materials to pass through.
- Standard qualitative cellulose filter paper provides reliable particle retention for gravity and vacuum filtration across routine laboratory workflows.
When your quality system requires documented specifications for every consumable, the grade data above provides the traceability your auditors expect. In this context, cotton linter cellulose provides the clean fiber background your general analytical methods need without the cost of specialty grades. Elevate the quality of your analytical data today by standardizing on a filtration product built to meet the exact specifications of your applications.
