Grade 1 Qualitative Filter Paper, Standard, 85mm Circle, 100/Pk SKU: 1001-085

Qualitative Filter Paper - 1001-085

Gravity filtration setups require paper that wets uniformly, seats flat in funnels, and retains particles at the rated threshold. Cellulose fiber matrix maintains structural integrity through standard gravity and light vacuum filtration conditions. In combination, 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.
• Uniform fiber distribution across the sheet ensures consistent particle retention from edge to center for reproducible filtration results.
• Pure cellulose fiber construction delivers consistent flow rates and predictable retention for general sample clarification and preparation.
• Manufactured from high-purity cotton linters, qualitative filter paper provides a clean filtration surface with minimal fiber shedding.
• Wet strength sufficient for gentle handling during precipitate transfer while maintaining the rapid flow rates of qualitative grades.

Whether your method requires simple clarification or precise gravimetric determination, the documented specifications above define what this paper delivers. For applications like these, broad grade availability lets you match retention, flow rate, and thickness to each specific application in your method library. Take control of your sample preparation variables and ensure that your data reflects the true nature of your work, rather than the quality of your consumables.
