Grade 113 Qualitative Filter Paper Wet-Strengthened, 46x57cm Sheet, 100/Pk SKU: 1113-917

Qualitative Filter Paper - 1113-917

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. Accordingly, quality-controlled production produces filter paper with the documented consistency that reproducible analytical and preparative methods demand.

Key Filter Paper Characteristics

• Wet strength sufficient for gentle handling during precipitate transfer while maintaining the rapid flow rates of qualitative grades.
• At 125g/m² nominal basis weight, the paper provides the mass uniformity needed for reproducible gravimetric determinations.
• Standard qualitative cellulose filter paper provides reliable particle retention for gravity and vacuum filtration across routine laboratory workflows.
• Pure cellulose fiber construction delivers consistent flow rates and predictable retention for general sample clarification and preparation.
• Uniform fiber distribution across the sheet ensures consistent particle retention from edge to center for reproducible filtration results.

If your teaching or research laboratory processes high volumes of routine samples, the documented flow rates above translate directly to throughput. Here, standard qualitative construction integrates into your existing funnel hardware, requiring no new equipment investment for reliable results. Secure your research outcomes by partnering with a filtration solution that understands your need for speed, accuracy, and reproducibility.
