Grade 113 Qualitative Filter Paper Wet-Strengthened, 110mm Circle, 100/Pk SKU: 1113-110

Qualitative Filter Paper - 1113-110

Teaching laboratories introducing filtration techniques need a paper grade that produces reliable results while remaining cost-effective for student use. Uniform pore distribution across the sheet area ensures consistent particle capture from center to edge during gravity filtration. By design, lot-level verification of retention, thickness, and ash content ensures predictable performance when scaling from method development to routine analysis.

Key Filter Paper Characteristics

• Standard qualitative cellulose filter paper provides reliable particle retention for gravity and vacuum filtration across routine laboratory workflows.
• Standard basis weight and thickness specifications provide predictable packing density for volumetric calculations in gravity funnels.
• Smooth surface finish supports clear visual inspection of retained material and clean separation from the collected filtrate.
• Pure cellulose fiber construction delivers consistent flow rates and predictable retention for general sample clarification and preparation.
• Strengthening treatment preserves paper structure through extended filtration runs where continuous wetting would weaken standard grades.

If your teaching or research laboratory processes high volumes of routine samples, the documented flow rates above translate directly to throughput. For this purpose, predictable retention and flow rate from a pure cellulose matrix give you a dependable filtration baseline for routine sample preparation. 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.
