Grade 2V Qualitative Filter Paper, Pre-Folded, 270mm Circle, 100/Pk SKU: 1202-270

Qualitative Filter Paper - 1202-270

Routine laboratory filtration demands a filter paper that delivers consistent particle retention without slowing sample throughput. Natural cellulose wettability eliminates the pre-wetting step required by hydrophobic membranes in aqueous sample filtration. 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 cellulose construction eliminates chemical treatment steps that could introduce background contamination in sensitive analytical methods.
• Uniform fiber distribution across the sheet ensures consistent particle retention from edge to center for reproducible filtration results.
• Smooth surface finish supports clear visual inspection of retained material and clean separation from the collected filtrate.
• Manufactured from high-purity cotton linters, qualitative filter paper provides a clean filtration surface with minimal fiber shedding.
• Basis weight of 97g/m² indicates the fiber mass per unit area that controls retention, flow rate, and wet strength.

When your analytical procedure specifies a particular grade, the retention and purity characteristics documented above confirm method compliance. Consistent sheet-to-sheet performance reduces the variability your operators encounter during high-volume daily filtration workflows. Elevate the quality of your analytical data today by standardizing on a filtration product built to meet the exact specifications of your applications.
