Qualitative Filter Paper - 989410107

Gravity filtration methods for removing suspended solids require filter paper that seats cleanly in funnels and retains particles consistently. Controlled fiber density produces documented flow rate and retention characteristics that remain consistent across production lots. From fiber selection through final inspection, the manufacturing process ensures every sheet meets the performance specifications of its grade.

Key Filter Paper Characteristics

• Standard wet strength is sufficient for conventional Buchner funnel and gravity filtration setups at moderate sample volumes.
• Pure cellulose fiber construction delivers consistent flow rates and predictable retention for general sample clarification and preparation.
• Nominal basis weight of 85g/m² reflects the fiber density that determines flow rate, retention, and mechanical handling characteristics.
• Standard qualitative cellulose filter paper provides reliable particle retention for gravity and vacuum filtration across routine laboratory workflows.
• Compatible with standard glass and plastic filter funnels, qualitative paper integrates into existing gravity filtration setups without modification.

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.
