Grade 597 Qualitative Filter Paper Standard Grade, Sheet, 580x580mm, 500/Pk SKU: 10311887

Qualitative Filter Paper - 10311887

Sample clarification before instrumental analysis starts with a filter paper that captures interfering particles without introducing extractable contamination. Pure cotton linter cellulose provides a uniform fiber matrix with consistent porosity and predictable retention across standard grade designations. As a result, lot-level verification of retention, thickness, and ash content ensures predictable performance when scaling from method development to routine analysis.

Key Filter Paper Characteristics

• Pure cellulose fiber construction delivers consistent flow rates and predictable retention for general sample clarification and preparation.
• Standard qualitative cellulose filter paper provides reliable particle retention for gravity and vacuum filtration across routine laboratory workflows.
• Standard cellulose construction provides reliable performance for gravity filtration and light vacuum applications.
• Wet strength sufficient for gentle handling during precipitate transfer while maintaining the rapid flow rates of qualitative grades.
• Particle retention rating of 4-7um defines the separation threshold for the application, determining which solids are captured and which pass through.

Your sample preparation workflow benefits from a filter paper whose performance is defined, documented, and consistent from one purchase to the next. To that end, wide retention range availability across the qualitative grade family lets you optimize each application in your sample preparation workflow. 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.
