Qualitative Filter Paper - 10311451
Routine laboratory filtration demands a filter paper that delivers consistent particle retention without slowing sample throughput. Available in circles, sheets, and prefolded formats to match specific funnel geometries and sample processing workflows. Lot-level verification of retention, thickness, and ash content ensures predictable performance when scaling from method development to routine analysis.
Key Filter Paper Characteristics
- Wet strength sufficient for gentle handling during precipitate transfer while maintaining the rapid flow rates of qualitative grades.
- Nominal basis weight of 85g/m² reflects the fiber density that determines flow rate, retention, and mechanical handling characteristics.
- Standard cellulose construction provides reliable performance for gravity filtration and light vacuum applications.
- Standard qualitative cellulose filter paper provides reliable particle retention for gravity and vacuum filtration across routine laboratory workflows.
- Unmodified cellulose surface provides natural hydrophilic properties for rapid wetting in aqueous filtration applications.
If your laboratory runs standardized filtration protocols, the lot-level consistency of this filter paper protects your method reproducibility. Standard qualitative construction integrates into your existing funnel hardware, requiring no new equipment investment for reliable results. Elevate the quality of your analytical data today by standardizing on a filtration product built to meet the exact specifications of your applications.
