Grade 597 1/2 Qualitative Filter Paper Folded (Prepleated), 110mm, 100/Pk SKU: 10311843

Qualitative Filter Paper - 10311843

Separating precipitates from analytical solutions requires a cellulose matrix with the right balance of retention and flow rate. Standard basis weight specifications provide predictable filter packing density for volumetric displacement calculations in funnel assemblies. In sum, lot-level verification of retention, thickness, and ash content ensures predictable performance when scaling from method development to routine analysis.

Key Filter Paper Characteristics

• Available in precut circles and sheet stock to match funnel sizes and custom cutting requirements across laboratory applications.
• Uniform fiber distribution across the sheet ensures consistent particle retention from edge to center for reproducible filtration results.
• Basis weight of 85g/m² indicates the fiber mass per unit area that controls retention, flow rate, and wet strength.
• Medium porosity cellulose matrix captures suspended solids while maintaining the throughput needed for efficient batch processing.
• Wet strength sufficient for gentle handling during precipitate transfer while maintaining the rapid flow rates of qualitative grades.

If your laboratory supports multiple research groups with varying filtration needs, this paper's broad applicability simplifies your procurement process. In response, economical unit cost at the pack quantities routine laboratories consume keeps your filtration budget aligned with actual throughput demands. Secure your research outcomes by partnering with a filtration solution that understands your need for speed, accuracy, and reproducibility.
