Grade 595 Qualitative Filter Paper Standard Grade, Circle, 125mm, 100/Pk SKU: 10311611

Qualitative Filter Paper - 10311611

Sample clarification before instrumental analysis starts with a filter paper that captures interfering particles without introducing extractable contamination. Uniform pore distribution across the sheet area ensures consistent particle capture from center to edge during gravity filtration. In sum, from fiber selection through final inspection, the manufacturing process ensures every sheet meets the performance specifications of its grade.

Key Filter Paper Characteristics

• Uniform fiber distribution across the sheet ensures consistent particle retention from edge to center for reproducible filtration results.
• Medium porosity cellulose matrix captures suspended solids while maintaining the throughput needed for efficient batch processing.
• Non-hardened paper balances effective particle retention with economical unit cost for high-volume routine laboratory use.
• Standard basis weight and thickness specifications provide predictable packing density for volumetric calculations in gravity funnels.
• Wet strength sufficient for gentle handling during precipitate transfer while maintaining the rapid flow rates of qualitative grades.

If you're transitioning from qualitative screening to quantitative gravimetric work, the documented ash content above confirms this paper's suitability. 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.
