Qualitative Filter Paper, Fast, 20-25 um, 110mm, 100/Pk SKU: CF15026

Qualitative Filter Paper - CF15026

Gravity filtration setups require paper that wets uniformly, seats flat in funnels, and retains particles at the rated threshold. Sample clarification before instrumental analysis starts with a filter paper that captures interfering particles without introducing extractable contamination. Consistent physical properties across the full sheet area support uniform filtration results in both gravity and vacuum applications.

Key Filter Paper Characteristics

• Controlled ash level at ≤0.15% ensures inorganic residue after ignition remains within the acceptable range for gravimetric procedures.
• Standard construction provides the soft, conformable surface that seats properly in gravity filtration funnels without edge leakage.
• Standard qualitative cellulose filter paper provides reliable particle retention for gravity and vacuum filtration across routine laboratory workflows.
• Pure cellulose fiber construction delivers consistent flow rates and predictable retention for general sample clarification and preparation.
• Medium porosity cellulose matrix captures suspended solids while maintaining the throughput needed for efficient batch processing.

If you're transitioning from qualitative screening to quantitative gravimetric work, the documented ash content above confirms this paper's suitability. 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.
