Grade 114V Pre-Pleated Filter Paper, 150mm Circle, 100/Pk SKU: 1214-150

Qualitative Filter Paper - 1214-150

Routine laboratory filtration demands a filter paper that delivers consistent particle retention without slowing sample throughput. Available in circles, sheets, and prefolded formats to match specific funnel geometries and sample processing workflows. From fiber selection through final inspection, the manufacturing process ensures every sheet meets the performance specifications of its grade.

Key Filter Paper Characteristics

• Wet-strengthened construction maintains paper integrity during prolonged vacuum and pressure filtration of aqueous samples.
• Pure cellulose fiber construction delivers consistent flow rates and predictable retention for general sample clarification and preparation.
• Available in precut circles and sheet stock to match funnel sizes and custom cutting requirements across laboratory applications.
• Manufactured to a basis weight of 190g/m², each sheet delivers the documented mass consistency that gravimetric methods require.
• Smooth surface finish supports clear visual inspection of retained material and clean separation from the collected filtrate.

If your laboratory runs standardized filtration protocols, the lot-level consistency of this filter paper protects your method reproducibility. For applications like these, 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.
