Grade 1 Qualitative Filter Paper, Standard, 385mm Circle, 100/Pk SKU: 1001-385

Qualitative Filter Paper - 1001-385

Isolating precipitates from reaction mixtures requires a cellulose matrix that captures solid material completely without premature filter blinding. Natural cellulose wettability eliminates the pre-wetting step required by hydrophobic membranes in aqueous sample filtration. 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

• Smooth surface finish supports clear visual inspection of retained material and clean separation from the collected filtrate.
• Nominal basis weight of 87g/m² reflects the fiber density that determines flow rate, retention, and mechanical handling characteristics.
• Non-hardened cellulose delivers the flow rates and retention that routine methods require at practical cost per determination.
• Ash content of 0.06% provides the documented blank value specification that quantitative analytical methods require.
• At 11um rated retention, the fiber matrix captures particles above the threshold while allowing smaller materials to pass through.

If your workflow includes both routine clarification and specialized quantitative methods, stocking this versatile grade reduces your inventory complexity. Addressing this directly, broad grade availability lets you match retention, flow rate, and thickness to each specific application in your method library. Elevate the quality of your analytical data today by standardizing on a filtration product built to meet the exact specifications of your applications.
