Grade 598 1/2 Qualitative Filter Paper Folded (Prepleated), 185mm, 50/Pk SKU: 10312247

Qualitative Filter Paper - 10312247

From student teaching labs to production QC departments, qualitative filter paper remains the workhorse for routine particle separation. 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

• Pure cellulose fiber construction delivers consistent flow rates and predictable retention for general sample clarification and preparation.
• Smooth surface finish supports clear visual inspection of retained material and clean separation from the collected filtrate.
• Wet strength sufficient for gentle handling during precipitate transfer while maintaining the rapid flow rates of qualitative grades.
• Manufactured from high-purity cotton linters, qualitative filter paper provides a clean filtration surface with minimal fiber shedding.
• Standard qualitative cellulose filter paper provides reliable particle retention for gravity and vacuum filtration across routine laboratory workflows.

When your budget requires balancing performance with cost efficiency, the documented consistency above ensures you're not paying for premium features you don't need. Sheet-to-sheet consistency means your training investment carries forward as new staff learn the same predictable filtration behavior. Elevate the quality of your analytical data today by standardizing on a filtration product built to meet the exact specifications of your applications.
