Grade 113V Pre-Pleated Filter Paper, Wet-Strengthened, 185mm Circle, 100/Pk SKU: 1213-185

Qualitative Filter Paper - 1213-185

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

Key Filter Paper Characteristics

• Standard basis weight and thickness specifications provide predictable packing density for volumetric calculations in gravity funnels.
• Non-hardened cellulose delivers the flow rates and retention that routine methods require at practical cost per determination.
• Uniform fiber distribution across the sheet ensures consistent particle retention from edge to center for reproducible filtration results.
• Available in precut circles and sheet stock to match funnel sizes and custom cutting requirements across laboratory applications.
• Enhanced wet strength allows vacuum filtration at higher differential pressures without risking paper rupture mid-run.

When your budget requires balancing performance with cost efficiency, the documented consistency above ensures you're not paying for premium features you don't need. In these cases, economical unit cost at the pack quantities routine laboratories consume keeps your filtration budget aligned with actual throughput demands. 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.
