Grade 114 Qualitative Filter Paper Wet-Strengthened, 400mm Circle, 100/Pk SKU: 1114-400

Qualitative Filter Paper - 1114-400

Separating precipitates from analytical solutions requires a cellulose matrix with the right balance of retention and flow rate. Natural cellulose wettability eliminates the pre-wetting step required by hydrophobic membranes in aqueous sample filtration. In combination, controlled manufacturing delivers the documented retention, flow rate, and physical consistency that analytical and preparative filtration methods require.

Key Filter Paper Characteristics

• Smooth surface finish supports clear visual inspection of retained material and clean separation from the collected filtrate.
• Nominal retention of 25um provides the particle size cutoff appropriate for the analytical or preparative separation method.
• Basis weight of 190g/m² indicates the fiber mass per unit area that controls retention, flow rate, and wet strength.
• Standard qualitative cellulose filter paper provides reliable particle retention for gravity and vacuum filtration across routine laboratory workflows.
• Wet strength sufficient for gentle handling during precipitate transfer while maintaining the rapid flow rates of qualitative grades.

Scaling your method from development to routine production requires paper consistency at every lot, and the specifications above provide that assurance. For exactly this reason, 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.
