Grade 113 Qualitative Filter Paper Wet-Strengthened, 500mm Circle, 100/Pk SKU: 1113-500

Qualitative Filter Paper - 1113-500

Gravity filtration setups require paper that wets uniformly, seats flat in funnels, and retains particles at the rated threshold. Smooth surface finish allows clear visual assessment of retained solids and supports clean separation of precipitates from filtrate. Taken together, rigorous quality control at every production stage ensures physical properties align with published grade specifications before distribution.

Key Filter Paper Characteristics

• Uniform fiber distribution across the sheet ensures consistent particle retention from edge to center for reproducible filtration results.
• Enhanced wet strength allows vacuum filtration at higher differential pressures without risking paper rupture mid-run.
• Standard qualitative cellulose filter paper provides reliable particle retention for gravity and vacuum filtration across routine laboratory workflows.
• Medium porosity cellulose matrix captures suspended solids while maintaining the throughput needed for efficient batch processing.
• Available in precut circles and sheet stock to match funnel sizes and custom cutting requirements across laboratory applications.

When your multi-site study requires comparable data across laboratories, papers manufactured to tight documented specifications ensure your results align. Economical unit cost at the pack quantities routine laboratories consume keeps your filtration budget aligned with actual throughput demands. Elevate the quality of your analytical data today by standardizing on a filtration product built to meet the exact specifications of your applications.
