Grade 3 Qualitative Filter Paper, Standard, 185mm Circle, 100/Pk SKU: 1003-185

Qualitative Filter Paper - 1003-185

Gravity filtration methods for removing suspended solids require filter paper that seats cleanly in funnels and retains particles consistently. Cellulose fiber matrix maintains structural integrity through standard gravity and light vacuum filtration conditions. Together, from fiber selection through final inspection, the manufacturing process ensures every sheet meets the performance specifications of its grade.

Key Filter Paper Characteristics

• Medium porosity cellulose matrix captures suspended solids while maintaining the throughput needed for efficient batch processing.
• Standard qualitative cellulose filter paper provides reliable particle retention for gravity and vacuum filtration across routine laboratory workflows.
• Uniform fiber distribution across the sheet ensures consistent particle retention from edge to center for reproducible filtration results.
• Manufactured from high-purity cotton linters, qualitative filter paper provides a clean filtration surface with minimal fiber shedding.
• Untreated cellulose construction provides the pure, unmodified surface appropriate for routine filtration and general sample preparation.

Whether your method requires simple clarification or precise gravimetric determination, the documented specifications above define what this paper delivers. Rapid wetting and uniform pore distribution reduce the setup time your operators spend preparing each filtration run. Elevate the quality of your analytical data today by standardizing on a filtration product built to meet the exact specifications of your applications.
