Grade 2V Qualitative Filter Paper, Pre-Folded, 125mm Circle, 100/Pk SKU: 1202-125

Qualitative Filter Paper - 1202-125

Routine quality control filtration across multiple product lines requires a filter paper that delivers consistent retention without batch-to-batch performance drift. Natural cellulose wettability eliminates the pre-wetting step required by hydrophobic membranes in aqueous sample filtration. Together, controlled manufacturing delivers the documented retention, flow rate, and physical consistency that analytical and preparative filtration methods require.

Key Filter Paper Characteristics

• At 8um rated retention, the fiber matrix captures particles above the threshold while allowing smaller materials to pass through.
• Standard construction provides the absorption and wicking characteristics that gravity-based filtration protocols require.
• Pure cellulose fiber construction delivers consistent flow rates and predictable retention for general sample clarification and preparation.
• Smooth surface finish supports clear visual inspection of retained material and clean separation from the collected filtrate.
• Standard basis weight and thickness specifications provide predictable packing density for volumetric calculations in gravity funnels.

Your sample preparation workflow benefits from a filter paper whose performance is defined, documented, and consistent from one purchase to the next. Sheet-to-sheet consistency means your training investment carries forward as new staff learn the same predictable filtration behavior. Make the decision for consistency and reliability, ensuring that your laboratory maintains its reputation for high-quality, error-free output.
