Grade 597 1/2 Qualitative Filter Paper Folded (Prepleated), 270mm, 100/Pk SKU: 10311852

Qualitative Filter Paper - 10311852

Laboratories processing dozens of samples daily need a qualitative filter paper that performs reliably from the first sheet to the last. Uniform pore distribution across the sheet area ensures consistent particle capture from center to edge during gravity filtration. From fiber selection through final inspection, the manufacturing process ensures every sheet meets the performance specifications of its grade.

Key Filter Paper Characteristics

• Manufactured from high-purity cotton linters, qualitative filter paper provides a clean filtration surface with minimal fiber shedding.
• Pure cellulose fiber construction delivers consistent flow rates and predictable retention for general sample clarification and preparation.
• Compatible with standard glass and plastic filter funnels, qualitative paper integrates into existing gravity filtration setups without modification.
• Uniform fiber distribution across the sheet ensures consistent particle retention from edge to center for reproducible filtration results.
• Standard construction provides the absorption and wicking characteristics that gravity-based filtration protocols require.

When your multi-site study requires comparable data across laboratories, papers manufactured to tight documented specifications ensure your results align. To support this, sheet-to-sheet consistency means your training investment carries forward as new staff learn the same predictable filtration behavior. Make the decision for consistency and reliability, ensuring that your laboratory maintains its reputation for high-quality, error-free output.
